dmaengine: mediatek: uart-apdma: Fix above 4G addressing TX/RX
The VFF_4G_SUPPORT register is named differently in datasheets,
and its name is "VFF_ADDR2"; was this named correctly from the
beginning it would've been clearer that there was a mistake in
the programming sequence.
This register is supposed to hold the high bits to support the
DMA addressing above 4G (so, more than 32 bits) and not a bit
to "enable" the support for VFF 4G.
Fix the name of this register, and also fix its usage by writing
the upper 32 bits of the dma_addr_t on it when the SoC supports
such feature.
