Chris Goldsworthy c3c2bb34ac ANDROID: arm64/mm: Add command line option to make ZONE_DMA32 empty
ZONE_DMA32 is enabled by default on android12-5.10, yet it is not
needed for all devices, nor is it desirable to have if not needed. For
instance, if a partner in GKI 1.0 did not use ZONE_DMA32, memory can
be lower for ZONE_NORMAL relative to older targets, such that memory
would run out more quickly in ZONE_NORMAL leading kswapd to be invoked
unnecessarily.

Correspondingly, provide a means of making ZONE_DMA32 empty via the
kernel command line when it is compiled in via CONFIG_ZONE_DMA32.
