[kvm-unit-tests PATCH v3 06/18] arm64: efi: Move run code into a function

[Andrew Jones <andrew.jones@linux.dev>]

Push the run code in arm/efi/run into a function named
uefi_shell_run() since it will create an EFI file system, copy
the test and possibly the DTB there, and create a startup.nsh
which executes the test from the UEFI shell. Pushing this
code into a function allows additional execution paths to be
created in the script. Also rename EFI_RUN to UEFI_SHELL_RUN
to pass the information on to arm/run that it's being called
from uefi_shell_run().
