drm/i915/bw: Extract icl_init_qgv_info()

Browse Source 
Simplify the initialization of QGV points info by extracting
the code to initialize the QGV points info from dram info based
on the memory type. This will reduce the complexity of the init
QGV info routine as we will be supporting new memory types in
future platforms.

v2: rebase after Ville's refactoring

v3: patch description updated
