// There are 2 sets of GPIO pins which could be routed to FSPICS0, FSPICLK, FSPID, FSPIQ, FSPIHD, FSPIWP.
// However, there is only one set of GPIO pins which could be routed to FSPIIO4, FSPIIO5, FSPIIO6, FSPIIO7.
// As default (when we are not going to use Octal SPI), we make use of SPI2_FUNC_NUM to route one of the 2 sets of GPIO pins to FSPICS0 ~ FSPIWP as follows.
