wifi: brcmfmac: Remove #ifdef guards for PM related functions
Use the new DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() macros to
handle the .suspend/.resume callbacks.
These macros allow the suspend and resume functions to be automatically
dropped by the compiler when CONFIG_SUSPEND is disabled, without having
to use #ifdef guards.
Some other functions not directly called by the .suspend/.resume
callbacks, but still related to PM were also taken outside #ifdef
guards.
The advantage is then that these functions are now always compiled
independently of any Kconfig option, and thanks to that bugs and
regressions are easier to catch.
