spi: spidev_test: clarify usage for --size
By default, spidev_test transmits the predetermined message default_tx.
Given the --size parameter, the given number of random bytes are
transmitted instead.
Make all the input options (random bytes, string, file) mutually
exclusive.
Clarify the help text for --size.
While at it, make the -p help text consistently lowercase.
