hwmon: (pmbus) Add tps40422 front-end driver For TI power management chip TPS40422, READ_TEMPERATURE_2 command is supported on page 1 of the chip, but the original driver(pmbus.c) only tried to detect this command on page 0, this will lead to a result that the temperature sensor in page 1 couldn't be detected. This change is to isolate the tps40422 driver from pmbus.c into a solo front-end driver.

docs: hwmon: 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.
