mfd: Use i2c_get_match_data() in a selection of drivers

Use preferred i2c_get_match_data() instead of of_match_device() and
i2c driver_data to get the driver match data. With this, adjust the
includes to explicitly include the correct headers.

mfd: lp87565: Fix Wvoid-pointer-to-enum-cast warning

'dev_type' is an enum, thus cast of pointer on 64-bit compile test with
W=1 causes:

lp87565.c:95:23: error: cast to smaller integer type 'enum lp87565_device_type' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]

mfd: Switch i2c drivers back to use .probe()

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

mfd: lp87565: Convert to i2c's .probe_new()

The probe function doesn't make use of the i2c_device_id * parameter so it
can be trivially converted.

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.

mfd: Add LP87565 PMIC support

The LP87565 chip is a power management IC for Portable Navigation Systems
and Tablet Computing devices. It contains the following components:

- Configurable Bucks(Single and multi-phase).
- Configurable General Purpose Output Signals (GPO).

The LP87565-Q1 variant device uses two 2-phase outputs configuration,
Buck0 is master for Buck0/1 output and Buck2 is master for Buck2/3
output.
