[PATCH] arm-bsp/edk2-firmware: workaround apcica changes

With the latest version of acpica (20260408), the following error is
being encountered in edk2 platforms for Arm SGI

valid parse opcode in OpcGenerateAmlOpcode)

Since this appears to be a debug message, and the relevant platforms are
a work in progress.  Work around this issue by removing the printf.
