arch/x86: smbios write 7 table using deterministic cache functions

This patch makes use of deterministic cache helper functions, for
example: cpu_get_cache_type(), cpu_get_cache_level() etc. helper
functions from arch/x86/cpu_common.c file.

Also, changed argument for get_number_of_caches() function that receives
cpu_get_max_cache_share() data directly.

Drop unused variables partitions, cache_line_size and number_of_sets as
struct cpu_cache_info.size  would provide the cache size directly.

TEST=Able to dump SMBIOS Table 7 with this CL, no changes seen in output.
Getting SMBIOS data from sysfs.
SMBIOS 3.0 present.
