Subject: [PATCH] dts: bcm2712: Extend PCIe range to encompass shared SRAM
The actual DT nodes from PCIe root complex to the RP1 endpoint
device do not include the sram shared memory range. While this
shared memory is not used yet, there's an error from mmio-sram
driver which cannot map the entire range.
Extend the range accordingly.
