[U-Boot] [PATCH] ARM: tegra: use a CPU freq that all SKUs can support

[Lucas Stach <dev@lynxeye.de>]

Hi Stephen,

I was just porting this change to barebox and stumbled upon a few errors
here.

The I2C address for this chip on Beaver is 0xc0, not 0x60. I don't know
about Cardhu.

This should be (0x4600 | TPS62366A_SET1_REG).

Same here.

Only with those fixed I can verify vdd_core to ramp up to 1,2V on
Beaver. Without the changes vdd_core stays at the default 1,16V.
