mfd: lpc_ich: Switch to generic p2sb_bar()
Instead of open coding p2sb_bar() functionality we are going to
use generic library. There is one more user en route.
This is more than just a clean-up. It also fixes a potential issue
seen when SPI BAR is 64-bit. The current code works if and only if
the PCI BAR of the hidden device is inside 4G address space. In case
when firmware decides to go above 4G, we will get a wrong address.
