cpu/x86: Add function to set `put_back_original_solution` variable
`put_back_original_solution` variable in mtrr.c is static, but there is
a need to set put_back_original_solution outside of mtrr.c in order to
let `remove_temp_solution` to drop any temporary MTRRs being set
outside `mtrr_use_temp_range()`, for example: `set_var_mtrr()` function
is used to set MTRRs for the ROM caching.
BUG=b:225766934
TEST=Able to build and boot google/redrix.
