[PATCH] lmb: Add StarFive JH-7110 SoC as requiring DMA below 4G

[E Shattow <e@freeshell.de>]

Platform drivers and hardware for StarFive JH-7110 SoC are not capable of
DMA access above 4GB. This was previously a problem for MMC access then
resolved by a workaround, since reverted in a3075db94d49 ("lmb: Reinstate
access to memory above ram_top"). The symptom of this is EFI boot failure
of GRUB from EFI System Partition on USB MSC with a starfive_visionfive2
board target that has the on-chip Cadence USB, tested with Pine64 Star64.

Restore the workaround with a dependency on LMB_LIMIT_DMA_BELOW_RAM_TOP.
