Since commit aed65af1cc ("drivers: make device_type const"), the driver
core can properly handle constant struct device_type. Move the mfd_dev_type
variable to be a constant structure as well, placing it into read-only
memory which can not be modified at runtime.

Process rise event last, to avoid stuck keys when multiple interrupts
are coalesced. This can happen typically when resuming from suspend
via power key press and holding the power button for a bit too short,
so that RISE an FALL IRQ flags are set before any interrupt routine
has a chance to run.
Input subsystem will interpret it as holding down a power key for
a long time, which leads to unintended initiation of shutdown UI
on some OSes.

Instead of only accepting the ti specific properties accept also
the standard property. For uniformity, search in the parent node
for the tag. The code for powering off is also isolated from the
rest in this file. So it is a pure Linux design decision to put it
here.

The sysctrl driver was looking for an instance of the PM2301
charger but this has been deleted from the kernel and is not
used with the U8500 systems any more. Drop the string.

A moderately busy release for SPI, the main core update was the merging
of support for multiple chip selects, used in some flash configurations.
There were also big overhauls for the AXI SPI Engine and PL022 drivers,
plus some new device support for ST.
There's a few patches for other trees, API updates to allow the
multiple chip select support and one of the naming modernisations
touched a controller embedded in the USB code.
- Support for multiple chip selects.
- A big overhaul for the AXI SPI engine driver, modernising it and
adding a bunch of new features.
- Modernisation of the PL022 driver, fixing some issues with submitting
messages while in atomic context in the process.
- Many drivers were converted to use new APIs which avoid outdated
terminology for devices and controllers.
- Support for ST Microelectronics STM32F7 and STM32MP25, and Renesas
RZ/Five.

crc_ccitt_false() was introduced in commit 0d85adb5fb ("lib/crc-ccitt:
Add CCITT-FALSE CRC16 variant"), but it is redundant with crc_itu_t().
Since the latter is more used, it is the one being kept.

The conversion to CLK_FRAC_DIVIDER_POWER_OF_TWO_PS uses wrong flags
in the parameters and hence miscalculates the values in the clock
divider. Fix this by applying the flag to the proper parameter.

Simplify probe() by replacing of_device_get_match_data() and ID lookup for
retrieving match data by i2c_get_match_data().
Some minor cleanups:
* Remove the trailing comma in the terminator entry for the ID
table making code robust against (theoretical) misrebases or other
similar things where the new entry goes _after_ the termination without
the compiler noticing.
* Move OF table near to the user.
