Pull RISC-V updates from Palmer Dabbelt:
- The PH1520 pinctrl and dwmac drivers are enabeled in defconfig
- A redundant AQRL barrier has been removed from the futex cmpxchg
implementation
- Support for the T-Head vector extensions, which includes exposing
these extensions to userspace on systems that implement them
- Some more page table information is now printed on die() and systems
that cause PA overflows
