[PATCH v6 3/5] EDAC/amd64: Extend family ops functions

[Naveen Krishna Chatradhi <nchatrad@amd.com>]

From: Muralidhara M K <muralimk@amd.com>

Create new family operation routines and define them respectively.
This would simplify adding support for future platforms.

Changes since v5:
split read_mc_regs for per family ops
Adjusted and Called dump_misc_regs for family ops

Changes since v4:
1. Modified k8_prep_chip_selects for ext_model checks
2. Add read_dct_base_mask to ops
3. Renamed find_umc_channel and addressed minor comments

Changes since v3:
1. Defined new family operation routines

Changs since v2:
1. new patch
