This patch updates the following properties in ospi node
-> reg - Linux driver expects AHB base addr in reg property.
- Fixed length of controller register set.
-> interrupt - Corrected the interrupt number for ospi.
-> cdns,fifo-depth - Corrected ospi fifo-depth property.

Add CPU Operating Performance Points (OPP) table and ACPU clock for
cpu0. This is needed by cpufreq driver to manage CPU frequency scaling.
e.g.
In the design if we have 72 as the multiplier and 33.333 MHz as the ref
frequency:
pllfreq = 33.33*72 = 2399.76 MHz
It is the pll output.
Now, with the integral divisors we can achieve:
2399.76 / 2 = 1199.88 MHz
2399.76 / 3 = 799.92 MHz
2399.76 / 4 = 599.94 MHz
2399.76 / 5 = 479.95 MHz
2399.76 / 6 = 399.96 MHz
2399.76 / 7 = 342.82 MHz
etc.
Therefore, some of them are chosen to be in the device tree.

This patch updates scriptaddr value to 512MB as having it at 32MB has high
chance of script corruption incase of bigger kernel.
Be aware that 512MB is used for SPL malloc area that's why images should be
loaded after SPL (the best after u-boot relocation).

Similar SCs but different wiring.
- dc_i2c is connected to X-PRC cards that's why label is required to have
an option to hook up some devices.
- Exactly identify i2c devices on x-prc boards.
In case of missing i2c connection devices won't be accessible.
- USB 0 should be device mode with super speed.
- USB 1 should be host mode.
- Fix i2c mux reset pin entry - commented, not verified.
- Fix i2c1 eeprom compatible string - it is an ST 128Kbit device.
Need to use atmel fallback.
- Fix si570 I2C slave address and add corresponding part numbers.
- Enable AMS for system monitoring.
- phy reset property should be commented because it will throw a
warning dump when called from context that can sleep.
No support for phys property (zynqmp phy driver) with SGMII.
Add is-internal-pcspma property required by uboot.

Idea is to have something what can be used for board bringup from
generic board perspective.
There is a violation compare to spec that FRU ID is ASCII8 instead of
binary format but this is really for having something to pass boot and
boot to OS which has better generating options.
Also time should be filled properly.
