mmc: rpmb: Fix driver routing memory alignment with tmp buffer

Fix mmc_rpmb_route_frames() implementation to comply with most MMC
drivers that expect some alignment of MMC data frames in memory.

When called from drivers/tee/optee/rpmb.c, the address passed is not
aligned properly. OP-TEE OS inserts a 6-byte header before a raw RPMB
frame which makes RPMB data buffer not 32bit aligned. To prevent breaking
ABI with OPTEE-OS RPC memrefs, allocate a temporary buffer to copy the
data into an aligned memory.

Many RPMB drivers implicitly expect 32bit alignment of the eMMC frame
including arm_pl180_mmci.c, sandbox_mmc.c and stm32_sdmmc2.c

phy: cadence: Add driver for Sierra PHY

Add a Sierra PHY driver with PCIe and USB support.
This driver is a port from the mainline linux driver.

The PHY has multiple lanes, which can be configured into
groups, and a generic PHY device is created for each group.

There are two resets controlling the overall PHY block, one
to enable the APB interface for programming registers, and
another to enable the PHY itself.  Additionally there are
resets for each PHY lane.

The PHY can be configured in hardware to read register
settings from ROM, or they can be written by the driver.

The sequence of operation on startup is to enable the APB
bus, write the PHY registers (if required)  for each lane
group, and then enable the PHY.  Each group of lanes
can then be individually controlled using the power_on()/
power_off() function for that generic PHY

One difference with the linux driver is that the PHY is
always reset after it is powered-on. This is because role
switching is not supported in u-boot and the cable
orientation is handled by the PHY reset.
