libpayload arm64: Allow board to define upper address limit on DMA
Instead of forcing boards to have DMA region below 4GiB, provide
Kconfig option DMA_LIM_EXCL that a board can use to set the upper
limit in MiB units on the address range reserved by DMA. By default,
this value is 0x1000 i.e. 4GiB limit on the DMA upper address.
BUG=None
BRANCH=None
TEST=Compiles successfully for rush. Default value is seen as 0x1000.
