Coverity detects an integer handling issue with BAD_SHIFT. The inline
function log2_ceil(u32 x) { return (x == 0) ? -1 : log2(x * 2 - 1); }
could return -1, which causes shifting by a negative amount value and
has undefined behavior. Add sanity check for the acm_header->size to
avoid shifting negative value.

This patch ensures that coreboot is able to take control of APs back
by doing a full AP re-initialization after FSP-S is done.
TEST=Able to see all cores available after booting to OS using below command
when coreboot is built with USE_INTEL_FSP_MP_INIT enable.
> cat /proc/cpuinfo
Without this CL :
shows only 1 core (only BSP)
With this CL :
shows all possible cores available (BSP + APs)

This patch makes init_cpus function external so that it can be used
in below scenarios:
1. When coreboot is doing MP initialization as part of
BS_DEV_INIT_CHIPS (exclude this call if user has selected
USE_INTEL_FSP_MP_INIT)
2. coreboot would like to take APs control back after FSP-S has done
with MP initialization based on user select USE_INTEL_FSP_MP_INIT
Also make sure post_cpus_init function is getting executed
unconditionally to update MTRR snapshot on all cores.

The VT-d architecture specification (Doc. D51397-011, Rev. 3.1) says:
BIOS implementations must report these remapping structure types in
numerical order. i.e., All remapping structures of type 0 (DRHD)
enumerated before remapping structures of type 1 (RMRR), and so forth.
So, update the corresponding code to adhere to the specification.
