In case of error returned by 'q6v5_xfer_mem_ownership', we must free
some resources before returning.
In 'q6v5_mpss_init_image()', add a new label to undo a previous
'dma_alloc_attrs()'.
In 'q6v5_mpss_load()', re-use the already existing error handling code to
undo a previous 'request_firmware()',

The Light Pulse Generator (LPG) is a PWM-block found in a wide range of
PMICs from Qualcomm. It can operate on fixed parameters or based on a
lookup-table, altering the duty cycle over time - which provides the
means for e.g. hardware assisted transitions of LED brightness.

Some LED controllers have support for autonomously controlling
brightness over time, according to some preprogrammed pattern or
function.
This adds a new optional operator that LED class drivers can implement
if they support such functionality as well as a new device attribute to
configure the pat
