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 sure what you mean here. Moving max_cap_width to the drv_data
/ configuration? Or do you mean something else?

This can probably go to qcom_llcc_config.

Match data (qcom_llcc_config) is fine, as qcom_llcc_cfg_program is only
called from .probe.

max_cap_width would be a new field that denotes the width of MAX_CAP
(which seems to always be at [31:n])
