Move the I2C read/write byte operations from the sbtsi hwmon driver into
a common sbtsi_xfer() function in tsi-core.c.
This decouples the hwmon sensor driver from the underlying bus transport,
preparing for I3C support in a subsequent patch.
This patch does not introduce any functional changes. The updates are
limited to code organization/cleanup and should not affect the runtime
behavior of the driver

Move SBTSI(Side-Band Temperature Sensor Interface) core functionality out
of the hwmon-only path and into drivers/misc/amd-sbi so it can be reused
by non-hwmon consumers.
I2C probe parsing is moved from drivers/hwmon/sbtsi_temp.c
into drivers/misc/amd-sbi/tsi.c under CONFIG_AMD_SBTSI. The core driver
stores struct sbtsi_data on the bus device and registers an auxiliary
device amd-sbtsi.temp-sensor.<addr> per target.
The current hwmon temp sensor will now require the CONFIG_AMD_SBTSI
configuration as a new dependency.
This split prepares the driver for additional interfaces while keeping
hwmon support in hwmon subsystem on top of common SBTSI core logic.
Add platform dependencies to clarify this driver is intended to run on
the BMC and not on the managed node.

- Move hwmon device sensor to misc as only power is reported through
hwmon sensor.

- This is done to utilize the protocol functionality into
other domains.
- Increase the scalability of the module with different bus(i2c/i3c)

This is done to support other functionality provided by the SBRMI, which
does not fit in the hwmon subsystem.
