regulator: tps65086: Select dedicated regulator config for chip variant

Some configurations differ between chip variants, e,g. the register
to control the on of state of LDOA1 and SWB2. Thus, it is necessary
to choose the correct configuration for a dedicated device.
If the wrong configuration was used, the LDOA1 output that was
disabled by the bootloader was enabled in Kernel again.

Each chip variant gets its dedicated configuration selected by
the chip ID previously collected from MFD probe function.
The VTT enum value (tps65086_regulators) is shifted because not all
chip variants have a separate SWB2 switch. Sometimes they are merged.
So the configuration possibilities differ, thus the regulator
configuration arrays have a different length.

mfd: tps65086: Read DEVICE ID register 1 from device

This commit prepares a following commit for the regulator part of the MFD.
The driver should support different device chips that differ in their
register definitions, for instance to control LDOA1 and SWB2.
So it is necessary to use a dedicated regulator description for a
specific device variant. Thus, the content from DEVICEID Register 1 is
used to choose a dedicated configuration between the different device
variants.

mfd: Replace HTTP links with HTTPS ones

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.
