06183ac5f5 pci: renesas: Fix BAR mapping on Gen3
Because the first PCIExAR(n) register is configured with the mapping,
It is the second PCIExAR(n) register that must be written with 0, not
the last one. Update the n from 4 to 1 to select the correct register.

d1998a9fde dm: treewide: Rename ofdata_to_platdata() to of_to_plat()
This name is far too long. Rename it to remove the 'data' bits. This makes
it consistent with the platdata->plat rename.

caa4daa2ae dm: treewide: Rename 'platdata' variables to just 'plat'
We use 'priv' for private data but often use 'platdata' for platform data.
We can't really use 'pdata' since that is ambiguous (it could mean private
or platform data).

Rename some of the latter variables to end with 'plat' for consistency.

41575d8e4c dm: treewide: Rename auto_alloc_size members to be shorter
This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.

Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

b6687e19f9 pci: Move some PCIe register offset definitions to a common header
Some PCI Express register offsets are currently defined in multiple
drivers, move them to a common header to avoid re-definitions and
as a pre-requisite for adding new PCIe driver.
While at it replace some spaces with tabs.

At present this method uses a non-const udevice pointer, but the call
should not modify the device. Use a const pointer.
