- Writing to arbitrary PMU chipctrl registers (required for common PHY PLL

- Requesting chipset/PLL-specific spurious signal avoidance modes.
- Querying clock frequency and latency.
Additionally, rather than updating legacy PWRCTL support to conform to the
new PMU interface:
- PWRCTL API is now provided by a bhnd_pwrctl_if.m interface.
- Since PWRCTL is only found in older SSB-based chipsets, translation from
bhnd(4) bus APIs to corresponding PWRCTL operations is now handled
entirely within the siba(4) driver.
- The PWRCTL-specific host bridge clock gating APIs in bhnd_bus_if.m have

zfs_write: fix problem with writes appearing to succeed when over quota
The problem happens when the writes have offsets and sizes aligned with
a filesystem's recordsize (maximum block size). In this scenario
dmu_tx_assign() would fail because of being over the quota, but the uio
would already be modified in the code path where we copy data from the
uio into a borrowed ARC buffer. That makes an appearance of a partial
write, so zfs_write() would return success and the uio would be modified
consistently with writing a single block.
That bug can result in a data loss because the writes over the quota

This commit fixes the bug by ensuring that the uio is not changed until
after all error checks are done. To achieve that the code now uses

now that uiocopy() has been updated in r326067 to use
