The 32-bit memory resource is needed for non-prefetchable memory

SM768) the system fails to allocate memory from this.
Checking the allocation against the datasheet, it looks like there
has been a mis-calcualation of the resource for the first memory
region (0x0060090000..0x0070ffffff) which in the data-sheet for
the fu740 (v1p2) is from 0x0060000000..0x007fffffff. Changing
this to allocate from 0x0060090000..0x007fffffff fixes the probing
issues.

Applied to riscv-dt-fixes, thanks!
[1/1] riscv: dts: fu740: fix size of pcie 32bit memory
https://git.kernel.org/conor/c/43d5f5d63699724d47f0d9e0eae516a260d232b4
I checked the numbers and they look correct per the v1p2 doc.
I added a T-b from IRC for Ron, added the cc: stable and fixed the
fixes tag while I was at it.
Thanks,
Conor.
Ok, great. I'll ping the fu-sdk people as well as this is probably
useful for the next release.
