This patch extends amdgpu.ip_block_mask to a Kconfig option as
well, that can be altered by user at build time for OS' that
do not permit passing dyanamic loading of amdgpu driver and also
passing command line arguments.
Note: This option to be used purely for debugging purposes and
amdgpu driver is not productised/tested extensively with any of its
blokcs disabled.
The default value of this option enables all IP's.
