Subject: net: phy: dp83822: Fix reset pin definitions

The SW_RESET definition was incorrectly assigned to bit 14, which is the
Digital Restart bit according to the datasheet. This commit corrects
SW_RESET to bit 15 and assigns DIG_RESTART to bit 14 as per the
datasheet specifications.

The SW_RESET define is only used in the phy_reset function, which fully
re-initializes the PHY after the reset is performed. The change in the
bit definitions should not have any negative impact on the functionality
of the PHY.
