[PATCH 3/4 v2] ARM: s3c64xx: Save/restore S3C64XX_MODEM_MIFPCON on suspend/resume to preserve LCD bypass state.

[Tomasz Figa]

This patch makes sure that the LCD bypass state is preserved during sleep mode.
It achieves this by saving the S3C64XX_MODEM_MIFPCON register, which is not
handled by any other code currently.
