drv/i2c/pi608gp: Fix types
In commit e59f18bf29a8 ("drivers/i2c: Add PI7C9X2G608GP PCIe switch
driver (pi608gp)"), there were some suggestions after it's been already
merged.
This patch addresses the points regarding the number types - fix of the
printk format strings, inclusion of 'stdint.h' and marking the set of
allowed values as constant.
BUG=none
TEST=Build OK, no behavioral changes in the pi608gp driver, console logs
without changes.
