[U-Boot] [PATCH v3 3/9] riscv: Define PLATFORM__CLEAR_BIT for generic_clear_bit()

[Bryan O'Donoghue]

riscv bitops.h provides a __clear_bit() but does not define
PLATFORM__CLEAR_BIT as a result generic_clear_bit() is used instead of the
architecturally provided __clear_bit().

This patch defines PLATFORM__CLEAR_BIT which means that __clear_bit() in
riscv bitops.h will be called whenever generic_clear_bit() is called - as
opposed to the default cross-platform generic_clear_bit().
