This is a simple RTC driver for the rv3032 from Microcrystal.
Just the basic functionality is implemented (no timer, alarm etc ..).

We need i2c first to set it to MIDDLE, then we need one of the pmics
so set them to LATE, only then we can attach iodomain which needs some
regulators exposed by the pmic so set it to LAST.

Some devices like Apple HID-over-SPI may contain more than one report
descriptors necessitating creation of multiple hidbus children.
Add indentificator of child devices to distinct them.
No functional changes intended.

Use correct resolution by compat table. If dtb is not defined use default 9 bit mode.
11 bit detection is called if 9 bit mode is used.
Sysctl resolution variable is added to change resolution in case.
Some sensors didn't pull ACK while reading from nonexistent registers and it caused I2C
read error and detect failure, so now detect failure does not cause driver break.

This merges TCA6416, TCA6408 drivers and adds PCA9555 support.
They handle 8 pin and 16 pin ICs with basic INPUT/OUTPUT functionality.
The register map is fairly similar so there is no point in having two
separate drivers.

My Adafruit PCF8523 RTC on either RPi2B or RPi3B+ failed to work around
80 ~ 90 % of boot-ups, by printing the following log lines.
nxprtc0: <NXP PCF8523 RTC> at addr 0xd0 on iicbus0
nxprtc0: cannot set up timer
Warning: no time-of-day clock registered, system time will not be set accurately
This is due to pcf8523_start_timer(sc) returned non-zero in
nxprtc_start() due to a register read failure of PCF8523_R_TMR_A_FREQ or
PCF8523_R_TMR_CLKOUT or a failure to program a new value.
The pause_sbt("nxpbat") sleep was too short and caused the register
access failures.

The register map is fairly similar, with one difference in the local
sensor temperature register width.
Both devices support reading two sensors - "local" and "remote".
While here add support for the latter one.
The ADT7461 doesn't update the temperature correctly, unless a write
transaction is done before every read.
Do just that as a workaround for this issue.
Tested on LS1046ARDB.

The EPSON RX-8035SA I2C RTC has a similar time register layout to the
ds1307 family, with some minor differences in bit positions, polarity
and control registers. Further generalize ds1307 to make it easier
to add more compatible chips and add support for the EPSON RX-8035SA.

The two implementations for the pca9548 switch and the pca9547 mux
seemed close enough so we can put them together and with a bit more
abstraction add pca9540 support.
While here apply a bit of consistency in variable and driver naming and
use device_has_property instead of the FDT-only OF_ variant.
This disconnects pca9547 from the build but does not yet delete it.
