Subject: [PATCH AUTOSEL 5.17 40/66] ARM: tegra: transformer: Drop reg-shift for Tegra HS UART

From: Svyatoslav Ryhel <clamor95@...il.com>

[ Upstream commit 79b788bfc787b60699d46b9e273b42ebe18336b3 ]

When the Tegra High-Speed UART is used instead of the regular UART, the
reg-shift property is implied from the compatible string and should not
be explicitly listed.
