u-boot: crm_regs: Anadig struct missing initial offset
The anadig_reg struct was not considering that the first meaningfull
register pll3_ctrl starts at the ANADIG base address + 0x10 of offset
Usually anadig_reg pointer is initialized to the ANADIG base address,
then creating an unaligned reference of the anadig refisters by an
offset of 0x10
