platform: qpnp-power-on: Add boot mode module parameter 



Warm boot runs may not last until the point where pon driver
has had a chance to read the warm boot registers. We need a way
to identify a warm boot in the crashes and hence we expect
bootloader to set this in kernel command line.
We may use this parameter later in the driver for
debug/verficiation purposes.
