riscv bitops.h provides a __set_bit() but does not define PLATFORM__SET_BIT as a result generic_set_bit() is used instead of the architecturally provided __set_bit().
This patch defines PLATFORM__SET_BIT which means that __set_bit() in x86 bitops.h will be called whenever generic_set_bit() is called - as opposed to the default cross-platform generic_set_bit().
