dt-bindings: dma: dma40: Prefer to pass sram through phandle

Extend the DMA40 bindings so that we can pass two SRAM
segments as phandles instead of directly referring to the
memory address in the second reg cell. This enables more
granular control over the SRAM, and adds the optiona LCLA
SRAM segment as well.

Deprecate the old way of passing LCPA as a second reg cell,
make sram compulsory.
