dt-bindings: firmware: google,gs101-acpm-ipc: add S2MPG11 secondary PMIC
...
In a typical system using the Samsung S2MPG10 PMIC, an S2MPG11 is used
as a sub-PMIC.
The interface for both is the ACPM firmware protocol, so update the
binding to allow the relevant node and update the example here to
describe the connection for both PMICs.
Since we have two PMICs here, but can not use the 'reg' property (as
the addressing is based on software, i.e. the ACPM firmware), the node
names reflect that with their respective suffix. The existing 'pmic'
therefore becomes deprecated in favour of 'pmic-1'.
While at it, update the example.

dt-bindings: firmware: google,gs101-acpm-ipc: convert regulators to lowercase
...
Using lowercase for the buck and ldo nodenames is preferred, as
evidenced e.g. in [1].
Convert the example here to lowercase before we add any bindings
describing the s2mpg1x regulators that will enforce the spelling.

dt-bindings: firmware: google,gs101-acpm-ipc: add ACPM clocks
...
The firmware exposes clocks that can be controlled via the
Alive Clock and Power Manager (ACPM) interface.
Make the ACPM node a clock provider by adding the mandatory
"#clock-cells" property, which allows devices to reference its
clock outputs.

The PMIC is supposed to be a child of ACPM, add it here to describe the
connection.
