dts: sm1: reduce the CMA reserved memory [1/1]

PD#SWPL-11208

Problem:
system would auto reboot because of low free memory(Unmovable type)

Solution:
reduce the CMA reserved memory.
1.reduce ion_cma_reserved from 128MB to 48MB.(DDR size == 1G)
2.remove vdin0_cma_reserved which is not used for sm1.

Verify:
test passed on sm1
