ftpmu010: fix relocation and enhance features
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.
