[PATCH v1 1/4] usb: phy: tegra: cosmetic fixes

[Svyatoslav Ryhel <clamor95@gmail.com>]

Change TEGRA_USB_HOSTPC1_DEVLC_PTS_HSIC to its literal value instead of
using the BIT macro, as it is an enumeration. Correct the spelling in the
comment and rename uhsic_registers_shift to uhsic_registers_offset.
These changes are cosmetic and do not affect code behavior.
