mb/google/brya: Increase Resizable BAR address space limit to 33 bits
The dGPU used for some Brya projects requests 33 bits of address
space for one of its BARs via the Resizable BAR mechanism
(requires 6GB).
This Kconfig is currently set at 32 bits for brya, so the allocation currently is capped at 32 bits (4GB). This patch sets the limit to 33
bits for brya boards, which is enough for the GPU.
BUG=b:214443809
TEST=all of the dGPU PCI BARs on agah can be successfully allocated
