Commit dd5c672d7ca9 ("arm64: bcmbca: Merge ARCH_BCM4908 to ARCH_BCMBCA")
removes config ARCH_BCM4908 as config ARCH_BCMBCA has the same intent.

Probably due to concurrent development, commit a0ba692072d8 ("leds:
bcm63138: add support for BCM63138 controller") introduces 'LED Support
for Broadcom BCM63138 SoC' that depends on ARCH_BCM4908, but this use was
not visible during the config refactoring from the commit above. Hence,
these two changes create a reference to a non-existing config symbol.

Adjust the LEDS_BCM63138 definition to refer to ARCH_BCMBCA instead of
ARCH_BCM4908 to remove the reference to the non-existing config symbol
ARCH_BCM4908.
