drivers/spi: add RPMC info to spi_flash struct
Fill 'rpmc_caps' struct inside the 'spi_flash' struct with the RPMC info
from the SFDP table.
TEST=On a board with a W74M12JW SPI flash chip, the 'rpmc_caps' struct
has the expected entries (RPMC available, OP2 extended status as polling
method, 4 RPMC counters, OP1 is 0x9b, and OP2 is 0x96).
