[PATCH v4 07/12] ARM: dts: aspeed: anacapa: Align PDB fan GPIO numbering

From: Rex Fu <rex.fu.amd at gmail.com>

Update the LPDB and RPDB fan GPIO line names to align with the platform
fan numbering scheme.

The LPDB fan GPIOs are named FAN0 through FAN4, while the RPDB fan GPIOs
are named FAN5 through FAN8. This keeps the GPIO line names consistent
with the fan inventory and platform-level fan numbering.
