[PATCH v2] configs: ls1021a: Append CMA configuration to bootargs

[Alison Wang]

The default reserved memory for CMA is high memory. If LPAE is enabled,
highmem pages are non-remapped and can not be used with
dma_alloc_coherent. Reserving low memory for CMA is needed for LS1021A.
This patch appends the related CMA configuration to bootargs.
