The of_clk_set_defaults() function is used in subsystems which can
be built as module. Add the missing symbol export entry so there
is no build errors like:
"ERROR: "of_clk_set_defaults" [drivers/i2c/i2c-core.ko] undefined!".

Fixes commit: 86be408b

On platforms with sizeof(int) < sizeof(long), writing a temperature
limit larger than MAXINT will result in unpredictable limit values
written to the chip. Avoid auto-conversion from long to int to fix
the problem.

For TI power management chip TPS40422, READ_TEMPERATURE_2 command is supported on
page 1 of the chip, but the original driver(pmbus.c) only tried to detect this command
on page 0, this will lead to a result that the temperature sensor in page 1 couldn't
be detected. This change is to isolate the tps40422 driver from pmbus.c into a solo
front-end driver.
