ARM: OMAP2+: Configure voltage controller for cpcap to low-speed
Looks like the i2c timings in high-speed mode do not work properly to
allow us to clear I2C_DISABLE bits for PRM_VOLTCTRL register and the
device reboots if I2C_DISABLE bits are cleared.
Let's configure the voltage controller i2c for low-speed mode as done in
the Motorola Mapphone Android Linux kernel. This saves us about 7mW of
power during retention compared to the high-speed values.
Let's also change the low-speed warning to pr_info about relying on the
bootloader configured low-speed values like we currently do.
