Usually, it is a good practice to add a commit message
(and not just the subject).

It will be highly appreciated if you can provide also an
explanation (in the commit message) of what and why it is done.

Thanks!

Well, to be honest, I thought it was all self explanatory, but maybe a
bit more context is required. I didn't notice I wrote twl4030 twice, so
I'll probably make a v2, including a description.

Thanks!

This enables the VMMC2 LDO, which powers the MMC2 device.
When the device starts from MMC2, this has already been enabled by the BootROM,
but when starting from peripheral boot (USB, UART), it is not the case.
