spi: rzv2h-rspi: Fix SPDR read access width for 16-bit RX
The RZ/V2H hardware manual (section 7.5.2.2.1) specifies that read access
size for the SPI Data Register (SPDR) are fixed at 32 bits. The
RZV2H_RSPI_RX macro for the 16-bit data path used readw(), violating
this requirement.
Switch to readl() for the 16-bit RX path to conform to the hardware
specification.
Fixes: 8b61c8919dff ("spi: Add driver for the RZ/V2H(P) RSPI IP")
