There are numbers of drivers for different PCA(L) series chip. They
share similiar register layout and control logic. This driver intends
to unify these drivers for PCA(L)xxxx series i2c gpio expanders.

For almost all STM32 GPIO controllers, the number of supported GPIO
pins managed by a single controller is 16 (with some exceptions for
fewer). However, the default for ngpios in the device tree bindings
for gpio-controllers is 32; leading to inaccuracies in handling GPIO
for these controllers, such as presenting too many GPIOs in the GPIO
shell. This patch redefines the default for ngpios for "st,stm32-gpio"
compatible devices to 16 and adds the correct ngpios for the few
exceptions Zephyr current supports.

LPC GPIO binding was wrong in that the reg address
on the simple soc bus was given as an index of the gpio ports
within a gpio controller. Fix this by putting the GPIO node
on the simple bus as a single node with the correct base address,
and make the ports children of this node.
Change the driver to get the port number from the reg address
instead of a custom property, and get base address from DT instead
of the SDK macro definition.

In some hardware designs it might happen that the reset signal
for the TLE9104 is not used only for this purpose, but instead for
instance to reset other devices at the same time. For such a hardware
design it is then necessary to make the reset GPIO optional. The reset
will have to be triggered earlier on.

This implements the daisy chain feature of the low side switch
BD8LB600FS. The daisy chaining is in hardware achieved via
connecting the MISO and MOSI lines of multiple instances of the IC
in a row. It is implemented in the driver through a variable number
of GPIOs on one instance. Therefore, one device tree instance of the
IC will handle multiple daisy chained physical instances.
