The EMC clock sources for Tegra210 currently incorrectly include pll_c2 and pll_c3. However, both of these should have been pll_mb as shown in the TRM. If Tegra210 happens to be configured such that the pll_mb is the default clock for the EMC, as configured by the bootloader, then this will cause a system hang on boot. This is because the kernel will disable the pll_mb when disabling unused clock as it appears to be unused when it is not.
Also add the additional pll_p clock source for the EMC.
