mb/google/brya: Increase Resizable BAR address space limit to 32 bits
The dGPU used for some Brya projects requests 32 bits of address space
for one of its BARs via the Resizable BAR mechanism. This Kconfig is
currently set at 29 bits for brya, so the allocation currently is
capped at 29 bits. This patch sets the limit to 32 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
