69f69d9b7f i2c: tegra-slave: Fix build for Linux v6.11 
In Linux v6.11, the 'platform_driver' structure 'remove' callback was
updated to return void instead of 'int'. Update the Tegra I2C Slave
driver accordingly to fix the build for Linux v6.11+ kernels.

3741667390 i2c: nvvrs11: Report power in milliWatts 
The unit of the voltage is in milliVolts and the current is in Amperes
for VRS11. So, the power can be reported in milliWatts which provides
higher resolution for better profiling.

a809f2cfb5 i2c: nvvrs11: Remove header file 
The header file for the NVIDIA I2C NVRS11 driver is only used by this
driver and so remove the header and include the necessary definitions in
the driver source. This avoids having to distribute a header file along
with the main source file.
