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.
