regulator: pfuze100: Convert the driver to DT-only
Since 5.10-rc1 i.MX is a devicetree-only platform, so simplify the code
by removing the unused non-DT support.

regulator: pfuze100: limit pfuze-support-disable-sw to pfuze{100,200}
Limit the fsl,pfuze-support-disable-sw to the pfuze100 and pfuze200
variants.
When enabling fsl,pfuze-support-disable-sw and using a pfuze3000 or
pfuze3001, the driver would choose pfuze100_sw_disable_regulator_ops
instead of the newly introduced and correct pfuze3000_sw_regulator_ops.

regualtor: pfuze100: correct sw1a/sw2 on pfuze3000
PFUZE100_SWB_REG is not proper for sw1a/sw2, because enable_mask/enable_reg
is not correct. On PFUZE3000, sw1a/sw2 should be the same as sw1a/sw2 on
pfuze100 except that voltages are not linear, so add new PFUZE3000_SW_REG
and pfuze3000_sw_regulator_ops which like the non-linear PFUZE100_SW_REG
and pfuze100_sw_regulator_ops.

regulator: pfuze100-regulator: Variable "val" in pfuze100_regulator_probe() could be uninitialized
In function pfuze100_regulator_probe(), variable "val" could be
initialized if regmap_read() fails. However, "val" is used to
decide the control flow later in the if statement, which is

regulator: pfuze100-regulator: provide pm_power_off_prepare handler
On some boards the SoC can use one pin "PMIC_STBY_REQ" to notify th PMIC
about state changes. In this case internal state of PMIC must be
preconfigured for upcomming state change.
It works fine with the current regulator framework, except with the
power-off case.

This patch is providing an optional pm_power_off_prepare handler
which will configure standby state of the PMIC to disable all power lines.

In my power consumption test on RIoTBoard, I got the following results:
power off without this patch:	320 mA
power off with this patch:	2   mA
suspend to ram:			40  mA

regulator: pfuze100: add support to en-/disable switch regulators
Add enable/disable support for switch regulators on pfuze100.

Based on commit 5fe156f1ca ("regulator: pfuze100: add enable/disable for
switch") which is reverted due to boot regressions by commit 464a5686e6
("regulator: Revert "regulator: pfuze100: add enable/disable for switch"").
Disabling the switch regulators will only be done if the user specifies
"fsl,pfuze-support-disable-sw" in its device tree to keep backward
compatibility with current dtb's [1].

regulator: Revert "regulator: pfuze100: add enable/disable for switch"
This reverts commit 5fe156f1ca.

Commit 5fe156f1ca ("regulator: pfuze100: add enable/disable for switch")
causes boot regression on some platforms such as imx6sl-evk and
imx6sll-evk.

After this commit the SW4 regulator will be turned
off and since it supplies the DDR voltage on these boards, a
kernel hang is observed.

Revert it to avoid breaking old dtb's.

e56566699c regulator: pfuze100: Simplify pfuze100_set_ramp_delay implementation
Simplify the equation to calculate ramp_delay.
Below equations are equivalent:
  ramp_delay = 25000 / (2 * ramp_delay);
  ramp_delay = 50000 / (4 * ramp_delay);
  ramp_delay = 25000 / (2 * ramp_delay);
  ramp_delay = 12500 / ramp_delay;
So we don't need to read BIT6 of rdev->desc->vsel_reg for applying different
equations.

Also use rdev->desc->vsel_reg instead of run-time calculate register address.

d9493234e2 regulator: pfuze100: Fix n_voltages setting for SW2~SW4 with high bit set
Current code adjust min_uV and uV_step but missed adjusting the n_voltages
setting.

When BIT6 is clear:
        n_voltages = (1975000 - 400000) / 25000 + 1 = 64
When BIT6 is set:
        n_voltages = (3300000 - 800000) / 50000 + 1 = 51

The n_voltages needs update because when BIT6 is set 0x73 ~ 0x7f are reserved.
When using regulator_list_voltage_linear, the n_voltages does matter here
because wrong n_voltages setting make the equation return wrong result.
e.g. if selector is 63, regulator_list_voltage_linear returns
     800000 + (50000 * 63) = 4000000
     It should return -EINVAL if the selector is in the range of 51 ~ 63.
