clk: at91: add sama5d2 audio PLL support
Commit 7310b976 ("clk: at91: fix compilation errors in sama5d2.c") and
follow-up commit ca3077068c ("clk: at91: delete dead i2s/audio code")
had deleted the i2s/audio clock related parts of the upstream driver.
This was mostly due to unwillingness on my part to understand the code
enough for porting them and because I deemed them unnecessary to support
in barebox. The former has changed and the latter is not totally true as
audio PLL derived clocks may be muxed as inputs for programmable and
generated clocks.
Port them over and mimize the diff to upstream.
