dmaengine: mediatek: mtk-uart-apdma: Rename support_33bits to support_ext_addr

In preparation for adding support for SoCs with APDMA IP versions
supporting more than 33 bits addressing, rename the support_33bits
variable to support_ext_addr to signal support for extended, above
4GB, addressing.

This change is cosmetic only, and brings no functional differences.
