soc: s3c: remove pm-debug hack

Browse source 
CONFIG_SAMSUNG_PM_DEBUG was only used on s3c24xx because of the
DEBUG_S3C24XX_UART dependency. Since s3c24xx is now gone, and nobody
ever noticed this option being missing from s3c64xx, it can be safely
removed as well.

Say Y here if you want verbose debugging from the PM Suspend and
Resume code. See <file:Documentation/arm/samsung-s3c24xx/suspend.rst>

Say Y here to enable the use of the SMDK LEDs on the baseboard
for debugging of the state of the suspend and resume process.
Note, this currently only works for S3C64XX based SMDK boards.

Enable the PM code's memory area checksum over sleep. This option
