driver/fast_spi: Refactor the SPI APIs (fill_xfer_fifo and drain_xfer_fifo)
The current fast_spi code uses memcpy for rw. The SPI flash read/write
has 4 byte limit, due to which the current 64 bit memcpy doesn't work.
Hence update rw ops to accommodate 64-bit mode operations.
BUG=b:242829490
TEST=Verified CSE RW update is successful in both 32-bit and 64-bit mode.
