powerpc/rtas: Fix watchdog driver temperature read functionality
Using the RTAS watchdog driver to read out the temperature crashes
on a PXCAB:
Unable to handle kernel paging request for data at address 0xfe347b50
Faulting instruction address: 0xc00000000001af64
Oops: Kernel access of bad area, sig: 11 [#1]
The wrong usage of "(void *)__pa(&temperature)" in rtas_call() is
removed by using the function rtas_get_sensor() which does the
right thing.
