This corrects the MISRA violation C2012-15.5:
A function should have a single point of exit at the end.
Introduced a temporary variable to store the return value to
ensure single return for the function.

This corrects the MISRA violation C2012-10.3:
The value of an expression shall not be assigned to an object with a
narrower essential type or of a different essential type category.
The condition is explicitly checked against 0U, appending 'U' and
typecasting for unsigned comparison.

Both operands of an operator in which the usual arithmetic
conversions are performed shall have the same essential type
category.
The condition is explicitly checked against 0U, appending 'U' and

Update the UFS clock rates as per the expected range
- Update the clock rates of "ufs_phy_clk" and "ufs_ref_pclk" to 26MHz
as 100MHz is not the valid clock rate for these two clocks.
- cpu_clock rate (908KHz) is not valid clock for UFS, hence skip setting
up UFS clocks to cpu_clock for SPP platform.

Following IOCTL IDs are required for UFS specific functionalities.
IOCTL ID - 40(IOCTL_UFS_TXRX_CFGRDY_GET)
This gives the Tx_Rx_config_rdy_signal_mon(0xF1061054) register value
which contains the Tx and Rx lanes configuration ready signal information.
IOCTL ID - 41(IOCTL_UFS_SRAM_CSR_SEL)
Select - 0(IOCTL_UFS_SRAM_CSR_SET)
This will allow to set sram control and status register (0xF106104C)
with the value provided by driver.
Select - 1(IOCTL_UFS_SRAM_CSR_GET)
This should return the sram control and status register (0xF106104C) value
to the driver.
UFS Host reset assert/de-assert(using SCMI) support is added.
register address : 0xF1260340
UFS PHY reset assert/de-assert(using SCMI) support is added.
register address : 0xF1061050

Add dummy implementation of power domain. There is dwc3 usb driver which
requires power domain to be setup and make sense to have interface prepared
even it is not doing anything. When this runs on real HW functionality will
be extended.

New SoC is a78 based with gicv3 and uart over pl011. Communication
interfaces are similar to Versal NET platform. System starts with AMD PLM
firmware which loads TF-A(bl31) to memory, which is already configured, and
jumps to it. PLM also prepare handoff structure for TF-A with information
what components were load and flags which indicate which EL level SW should
be started.
