kernel: Move to Linux v5.4.48-openpower1
This adds secure boot support backported from upstream and enables it
in the configuration.
Appearing in the backports is a patch to disable STRICT_KERNEL_RWX so
it drops out of the configuration.
Backported patches to support secureboot:
powerpc/ima: Fix secure boot rules in ima arch policy
powerpc/ima: Indicate kernel modules appended signatures are enforced
powerpc/xmon: Allow listing and clearing breakpoints in read-only mode
powerpc: Load firmware trusted keys/hashes into kernel keyring
x86/efi: move common keyring handler functions to new file
powerpc: expose secure variables to userspace via sysfs
powerpc/powernv: Add OPAL API interface to access secure variable
powerpc/ima: Update ima arch policy to check for blacklist
ima: Check against blacklisted hashes for files with modsig
certs: Add wrapper function to check blacklisted binary hash
ima: Make process_buffer_measurement() generic
powerpc/ima: Define trusted boot policy
powerpc: Detect the trusted boot state of the system
powerpc/ima: Add support to initialize ima policy rules
powerpc: Detect the secure boot mode of the system
