hwmon updates for v5.14

Browse source 
New drivers:
 - Delta DPS920AB
 - Flex PIM4006, PIM4328 and PIM4820
 - MPS MP2888
 - Sensirion SHT4X
 
 Added chip support to existing drivers:
 - Flex BMR310, BMR456, BMR457, BMR458, BMR480, BMR490, BMR491, and BMR492
 - TI TMP1075
 - Renesas ZLS1003, ZLS4009 and ZL8802
 
 Other;
 - Dropped explicit ACPI support for MAX31722 and LM70;
   the APIC IDs in those drivers do not exist.
 - Support set_trips() callback into thermal subsystem
 - Minor fixes and improvements in various drivers

* PMBUS_READ_STATUS_AFTER_FAILED_CHECK
*
* Some PMBus chips end up in an undefined state when trying to read an
* unsupported register. For such chips, it is necessary to reset the
* chip pmbus controller to a known state after a failed register check.
* This can be done by reading a known register. By setting this flag the
* driver will try to read the STATUS register after each failed
* register check. This read may fail, but it will put the chip in a
* known state.

/*
* PMBUS_NO_WRITE_PROTECT
*
* Some PMBus chips respond with invalid data when reading the WRITE_PROTECT
* register. For such chips, this flag should be set so that the PMBus core
* driver doesn't use the WRITE_PROTECT command to determine its behavior.
*/

* PMBUS_USE_COEFFICIENTS_CMD

* When this flag is set the PMBus core driver will use the COEFFICIENTS
