4732b6cdb7 misc: Reflect changes of arm bootloader name 
With https://gem5-review.googlesource.com/c/public/gem5/+/22687 the
VExpress_GEM5_Base platform is changing the required bootloader name
by removing the _emm suffix.
While this had been changed in the prebuilt binaries in gem5.org, it
hadn't in the bootloader makefiles or in other utility functions.

The patch is not completely removing the _emm bootloaders since those
are still used by VExpress_EMM and VExpress_EMM64 platforms.

47326f5422 arm: Bootloader fix for v8 over 16 cores 
Previous code used a smaller 4 bit mask to test the MPIDR-EL1 register.
The bitmask was extended to support greater than 16 cores.

612f8f074f arm: Add support for ARMv8 (AArch64 & AArch32) 
Note: AArch64 and AArch32 interworking is not supported. If you use an AArch64
kernel you are restricted to AArch64 user-mode binaries. This will be addressed
in a later patch.

Note: Virtualization is only supported in AArch32 mode. This will also be fixed
in a later patch.
