[PATCH 2/3] ARM: rockchip: dmc: substract ROCKCHIP_DRAM_TFA_CARVE_OUT from memory regions

[Sascha Hauer]

With 516447c05c rockchip_ram() gets the physical memory base/size
instead of ROCKCHIP_DRAM_TFA_CARVE_OUT already honored. With this we
not only have to add ROCKCHIP_DRAM_TFA_CARVE_OUT to membase, but also
substract it from memsize. The latter was forgotten, add it now.

Fixes: 516447c05c ("ARM: rockchip: separate physical DRAM start from usable start")
