Implement necessary support for the LLCC control on the SAR1130P and
SAR2130P platforms. These two platforms use different ATTR1_MAX_CAP
shift and also require manual override for num_banks.

I'm not going to verify each and every value, but this generally
looks good

[...]

> +		.max_cap_shift	= 0x0e,

This should be a decimal 14 (as it's denoting the bit position)
