1. ftpmu010.h: fix and add definitions
   Enhanced for more features and asm related support
   according to datasheet.

   Note:
    - FTPMU010_PDLLCR0_HCLKOUTDIS is "incorrect" in datasheet.
    - FTPMU010_PDLLCR0_DLLFRANG is only 1 bit at bit #19. (not 20-19)
    - FTPMU010_PDLLCR0_HCLKOUTDIS is 4 bits at bit #20. (not 24-21)

2. ftpmu010.c: enhance features and fix relocation
   - The following functions is added for pmu features.
     ftpmu010_mfpsr_select_dev()
     ftpmu010_sdramhtc_set()
   - This patch also fix the declare statement for relocation.
