RAPL MSR interface supports 2 power limits for package domain, and 1 power
limit for other domains, while RAPL MMIO interface supports 2 power limits
for both package and dram domains.
And when 2 power limits are supported, the FW_LOCK bit is in bit 63 of the
register, instead of bit 31.
Remove the assumption that only pakcage domain supports 2 power limits.
And allow the RAPL interface driver to specify the number of power limits
supported, for every single RAPL domain it owns..

RAPL MMIO interface uses 64 bit registers, thus force use 64 bit register
for all the RAPL code.

Split intel_rapl.c to intel_rapl_common.c and intel_rapl_msr.c, where
intel_rapl_common.c contains the common code that can be used by both MSR
and MMIO interface.
intel_rapl_msr.c contains the implementation of RAPL MSR interface.
