The unit for TPDM DSB element size is bits. So rename the property:
qcom,dsb-element-size => qcom,dsb-element-bits
This also makes it consistent with the naming for the CMB element
size property.
There is no tpdm node in any DT as of now. Make this change before
any tpdm node is added to DT.

Add property "qcom,cmb_msr_num" to support CMB MSR(mux select register)
for TPDM. It specifies the number of CMB MSR registers supported by
the TDPM.

Add property "qcom,cmb-elem-bits" to support CMB(Continuous
Multi-Bit) element for TPDM. The associated aggregator will read
this size before it is enabled. CMB element size currently only
supports 8-bit, 32-bit and 64-bit. Because the existing example
tpdm "tpdm@684c000" which only supports dsb sub-unit, I introduce
a new example "tpdm@6c29000" to describe the usage of this new
property.

Documentation/process/license-rules.rst and checkpatch expect the SPDX
identifier syntax for multiple licenses to use capital "OR". Correct it
to keep consistent format and avoid copy-paste issues.
Correct also the format // -> .* in few Allwinner binding headers as
pointed out by checkpatch:
WARNING: Improper SPDX comment style for 'include/dt-bindings/reset/sun50i-h6-ccu.h', please use '/*' instead
