LoongArch: set CONFIG_CMA_SIZE_MBYTES to 0

LoongArch inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/IBQ4JL


CVE: NA

--------------------------------

When CONFIG_CMA_SIZE_MBYTES is not zero and its value is small,
error log appear in dmesg as following:
[12689.920994][ T2178] cma: cma_alloc: reserved: alloc failed, req-size: 4 pages, ret: -12
[12689.934128][ T2178] cma: cma_alloc: reserved: alloc failed, req-size: 4 pages, ret: -12

So set CONFIG_CMA_SIZE_MBYTES to 0 to hide the error log.
