ARM: S3C24XX: Locate kernel at 0x30108000 if PM_H1940 is enabled

Browse Source 
If PM_H1940 is enabled, kernel _must_ be located upper then 0x30008000,
because this area (0x30000000-0x30100000) can be used by bootloader. If
kernel is located at 0x30008000, bootloader will corrupt kernel's code during
resume.
