[PATCHv9 7/8] ARM: OMAP: PM: update target fpwrst to what pwrdm can reach

[Tero Kristo <t-kristo@ti.com>]

As the code within pwrdm_set_fpwrst is updating powerstate and logic
states according to powerdomain capabilities, it may alter the target
fpwrst also. Update the target fpwrst status according to these checks,
otherwise rest of the code in this function will malfunction.
