Rename all fields with 'freq' as 'clk_freq' to follow the MIPI
specification and avoid confusion between bus clock and audio clocks.
No functionality change.

The MIPI DisCo specification for SoundWire defines the
"mipi-sdw-link-N-subproperties" for slaves and
"mipi-sdw-master-N-subproperties" for controllers. This is a mistake
that was not identified until now.
Existing Intel DSDT tables use 'link' everywhere, and the MIPI spec
will be updated to deprecate "mipi-sdw-master-N-subproperties"
Fix to parse firmware information on existing devices. If we ever see
a system with 'master-N-subproperties' I guess we'll have to try both.

Linux code style doesn't expect empty lines before or after braces and
gives warning:
CHECK: Blank lines aren't necessary after an open brace '{'
CHECK: Blank lines aren't necessary before a close brace '}'
Fix these instances in soundwire core

Use Linux style. In some cases parenthesis alignment is modified to
keep the code readable.

MIPI Discovery And Configuration (DisCo) Specification for SoundWire
specifies properties to be implemented for SoundWire Masters and
Slaves. The DisCo spec doesn't mandate these properties. However,
SDW bus cannot work without knowing these values.
The helper functions read the Master and Slave properties.
Implementers of Master or Slave drivers can use any of the below
three mechanisms:
a) Use these APIs here as .read_prop() callback for Master
and Slave
b) Implement own methods and set those as .read_prop(), but invoke
APIs in this file for generic read and override the values with
platform specific data
c) Implement ones own methods which do not use anything provided
here
