spi: microchip-core: use XOR instead of ANDNOT to fix the logic

Use XOR instead of ANDNOT to fix the logic. The current approach with
(foo & BAR & ~baz) is harder to process, and it proved to be wrong,
than more usual pattern for the comparing misconfiguration using
((foo ^ baz) & BAR) which can be read as "find all different bits
between foo and baz that are related to BAR (mask)". Besides that
it makes the binary code shorter.

Function                                     old     new   delta
mchp_corespi_setup                           103      99      -4
