Cong Dang f3107fca54 memory: renesas-rpc-if: Clear HS bit during hardware initialization
[ Upstream commit 5192481f90 ]

According to the datasheet, HS bit should be specified to 1 when using
DMA transfer. As DMA transfer is not supported, it should be cleared to
0.

Previously, the driver relied on the HS bit being cleared by prior
firmware but this is not always the case.

Fix this by ensuring the bit is cleared during hardware initialization.
