Vedashree Vidwans f91708325e tegra: hwpm: move common hals to common path
Allowlist, get IP/resource info and perfmux disable HALs defined in t234
specific files do not require any chip specific details.
Move such functions to common files. This way common functions can be
reused by future chips, reducing maintainability of these functions.
Rename linux specific get_resource_info and get_floorsweep_info
functions to avoid multiple definitions.
