In nand_wait_ready there is a loop that includes a NULL check for
chip->dev_ready before it is dereferenced. Use a NULL check once the
loop is exited as well to cover the case where it exits due to a timeout
and it is therefore not known if chip->dev_ready is NULL or not.

Add UFS driver for UFS controller present on Renesas R-Car X5H R8A78000.
The controller uses different initialization code compared to previous
generation UFS controller present in Renesas R-Car S4 R8A779F0, and the
majority of the driver is the initialization, hence a new driver.

A UFS device needs its bRefClkFreq attribute set to the correct value
before switching to high speed. If bRefClkFreq is set to the wrong
value, all transactions after the power mode change will fail.
The bRefClkFreq depends on the host controller and the device.
Query the device's current bRefClkFreq and compare with the ref_clk
specified in the device-tree. If the two differ, set the bRefClkFreq
to the device-tree's ref_clk frequency.

Commit d232d7fdbf ("ufs: core: sync ufshci.h with Linux v6.12") updated
the Data Direction values from bitmask values to simple enumerations.
Before:
enum {
UTP_NO_DATA_TRANSFER = 0x00000000,
UTP_HOST_TO_DEVICE = 0x02000000,
UTP_DEVICE_TO_HOST = 0x04000000,
};
Updated:
enum utp_data_direction {
UTP_NO_DATA_TRANSFER = 0,
UTP_HOST_TO_DEVICE = 1,
UTP_DEVICE_TO_HOST = 2,
};
However, the U-Boot code still uses these values directly without shifting,
and resulting in wrong bitfield placement in the Transfer Request
Descriptor.
This fixes the issue by applying the necessary shift to align the value.
