i.mx6dl and i.mx6q share the same ARM2 board due to the pin-pin
compatible between them.

WAIT mode and DVFS still have some defects, we need
to disable it by default until we make them works.

DVFS-CORE should be enabled at boot by default.

When DVFS_CORE is enabled, the following command reports incorrect frequency:
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq
Fix this by ensuring the CPUFREQ does not change the frequency
when DVFS_CORE is active. And DVFS-CORE informs CPUFREQ of the
change done to CPU frequency.

This reverts commit 564e25cb10cd827ea3fa5cda2487fd978f08bbd7.
Sourcing ARM_CLK from PLL2_PFD_400M is causing issues when setting
the ARM_PODF. So for now source arm_clk from PLL1_SYS_MAIN only.

When CPU frequency is below 400MHz (due to CPUFREQ or dvfs-core), we can source
pll1_sw_clk from PLL2_PFD_400M and disable PLL1. This can save some power.
Fixed warnings in dvfs_core driver.

loops_per_jiffy is a global variable for non-smp platforms.
For SMP platforms, loops_per_jiffy is a per_cpu variable.
Fix dvfs_core to adjust loops_per_jiffy for both configurations.
