clk: at91: pmc: Wait for clocks when resuming

[ Upstream commit 960e1c4d93be86d3b118fe22d4edc69e401b28b5 ]

Wait for the syncronization of all clocks when resuming, not only the
UPLL clock. Do not use regmap_read_poll_timeout, as it will call BUG()
when interrupts are masked, which is the case in here.
