soc/amd/stoneyridge: Remove dev_find_slot where possible
The procedure dev_find_slot has 3 main uses. To find configuration
(devicetree), to verify if a particular device is enabled at build \
time, and to get the address for PCI access while in bootblock/romstage.
The third use can be hidden by using macros defined in pci_devs.h,
making it very clear what PCI device is being accessed. replace the
temporary pointers to device used with PCI access with SOC_XXX_DEV where
XXX is the device being accessed, and remove the setting of the temporary
pointers.
BUG=b:117917136
TEST=Build grunt.
