spi: rzv2m-csi: Improve data types, casting and alignment

"unsigned int" is more appropriate than "int" for the members
of "struct rzv2m_csi_priv".
Using void* rather than u8* for txbuf and rxbuf allows for
the removal of some type casting.
Remove the unnecessary casting of "data" to "struct rzv2m_csi_priv*"
in function "rzv2m_csi_irq_handler".
Also, members "bytes_per_word" and "errors" introduce gaps
in the structure.
Adjust "struct rzv2m_csi_priv" and its members usage accordingly.
