mmc: tmio: sdhi: Add DMA transfer address alignment check at writing
In R-Car Gen 3, there is a DMA controller restriction of SDHI.
When the transfer exceeding the 4 kByte boundary is performed while
the DRAM address is not 128 byte aligned, the bus is occupied.
This patch avoids this.

Those two boards are supposed to be run with a single u-boot binary.
There are notable differences though - HSC uses DSA switch (which
phy_id == 0x0) and DCC (DP83848C).
After the commit 3bf135b6c367

with phy_id == 0 are not created in U-Boot anymore. This caused regression
on HSC.

the phy_id is not assessed anymore. This approach works on both boards.
