pwm: pxa: Depend on OF and simplify accordingly

Browse Source 
The SoCs that this driver actually works on all imply OF already. (ARM
selects USE_OF unless some archs are enabled that cannot be selected
together with ARCH_PXA or ARCH_MMP, ARM64 and RISCV select OF.)

With OF known to be enabled a few conditionals in the driver can be
simplified.
