Introduced macros to define HWPM aperture types perfmon, perfmux and
broadcast.
Added new enum to define element type.
IP perfmux and IP broadcast are handled in similar way. Whereas, HWPM
perfmux should use HWPM perfmon functions.
Updated hwpm structures are as below
Parent HWPM structure
-> Active chip structure
-> Array of IPs
-> HALs
IP structure
-> Array of instances
-> Array of instance info with respect to perfmon, perfmux, broadcast
-> Instance mask : indicates available instances
-> reserved status
Instance structure
-> Array of element info with respect to perfmon, perfmux, broadcast
-> Array of corresponding element structures
-> Element mask : indicates available elements in the instance
Element structure
-> Aperture address details
-> DT node / MMIO details
Update all functions to use new HWPM structures.
Update hwpm_probe to include force IP enable step.
