Subject: [PATCH] riscv: errata: Make ERRATA_STARFIVE_JH7100 depend on !DMA_DIRECT_REMAP

Similar to the Renesas RZ/Five[1] the JH7100 SoC needs the non-portable
CONFIG_DMA_GLOBAL_POOL enabled which is incompatible with DMA_DIRECT_REMAP
selected by RISCV_ISA_ZICBOM.

[1]: commit 31b2daea0764 ("soc: renesas: Make RZ/Five depend on !DMA_DIRECT_REMAP")

Fixes: 64fc984a8a54 ("riscv: errata: Add StarFive JH7100 errata")
