The ULPI_UTMI_SEL bit in the DWC2 driver was set incorrectly. According
to the datasheet [1], this bit should be set to 0 for UTMI interface and 1
for ULPI interface. The existing code had this logic reversed,
causing the interface selection to be incorrect.
This commit corrects the ULPI_UTMI_SEL bit setting to match the
datasheet's description. Referencing the kernel's code [2] also confirms
this fix.
