[PATCH v3 0/7] riscv: Clean up timer drivers

[Sean Anderson]

This series cleans up the timer drivers in RISC-V and converts them to DM.

This series depends on [1]. This series needs to be tested! I have only tested
it on QEMU and the K210. Notably, this means that the HiFive and anything Andes
is completely untested. CI for this series is located at [2].

Changes in v3:
- Don't initialize the IPI in spl_invoke_opensbi. Further testing has
  revealed it to be unnecessary.
- Rebase

Changes in v2:
- Remove RISCV_RDTIME KConfig option
- Split Kendryte binding changes into their own commit
- Fix SiFive CLINT not getting tick-rate from rtcclk
