[PATCH v3 0/4] dmaengine: dw-axi-dmac: Fix burst encoding, LLI dump and priority

[Jia Wang]

This series fixes AXI burst length encoding, an out-of-bounds access in
the error-path LLI dump, and the CH_CFG2 channel priority field position.

It also converts register field definitions and programming to GENMASK()
and FIELD_PREP().

The series was tested with dmatest on all eight channels using
snps,axi-max-burst-len = <256>. All channels completed without errors. It
was also build-tested on RISC-V with CONFIG_DW_AXI_DMAC as both a module
and built-in.
