ARM: tegra124: Clear IDDQ when enabling PLLC

Enabling a PLL while IDDQ is high. The Linux kernel checks for this
condition and warns about it verbosely, so while this seems to work
fine, fix it up according to the programming guidelines provided in
the Tegra K1 TRM (v02p), Section 5.3.8.1 ("PLLC and PLLC4 Startup
Sequence").
