msm: Deprecate use of MSM_DEBUG_UART1,2,3 for low level debug

This patch is based off "msm: Consolidate and move DEBUG_LL
to generic ARM Kconfig" where use of MSM_DEBUG_UART1,2,3 is
deprecated and instead have one Kconfig per target/board.

The choice menu for selecting the DEBUG UART still remains
in mach-msm folder and has not been moved under DEBUG_LL
unlike the original patch.

Remove machine_is_*() checks from uncompress.h for various
targets and instead use CONFIG_SERIAL_MSM_HSL to identify
the UART core.
