Change testbus default config, dump additional testbus
registers and ufs phy regs along with other debug vendor
specific registers. These additional info are useful
in debugging link related failures.

It's useful to dump phy registers on failure to debug
link issues. Export a new ops for the ufs driver to invoke
during link failures.

Currently the code passes on the error value it receives from the
individual property getters. This causes the read of uevent to fail.
Instead convert those errors to -ENODATA which the power supply
framework handles graciously and keeps the read of uevent entry from
failing. It simply skips reporting that property in uevent.

Add support of monitoring runtime phone power. Driver configures two
threshold values and receives notifications when phone power
crosses either high or low threshold. Driver then sends indication to
WLAN FW, which will vote for different regulator power mode based on the
indication.

We don't want the writeback triggered from the journal commit (in
data=writeback mode) to cause the journal to abort due to
generic_writepages() returning an ENOMEM error. In addition, if
fsync() fails with ENOMEM, most applications will probably not do the
right thing.
So if we are doing a data integrity sync, and ext4_encrypt() returns
ENOMEM, we will submit any queued I/O to date, and then retry the
allocation using GFP_NOFAIL.
