Subject: [PATCH AUTOSEL 5.4 14/73] ARM: imx: rename DEBUG_IMX21_IMX27_UART to DEBUG_IMX27_UART

From: Lukas Bulwahn <lukas.bulwahn@...il.com>

[ Upstream commit b0100bce4ff82ec1ccd3c1f3d339fd2df6a81784 ]

Since commit 4b563a066611 ("ARM: imx: Remove imx21 support"), the config
DEBUG_IMX21_IMX27_UART is really only debug support for IMX27.

So, rename this option to DEBUG_IMX27_UART and adjust dependencies in
Kconfig and rename the definitions to IMX27 as further clean-up.

This issue was discovered with ./scripts/checkkconfigsymbols.py, which
reported that DEBUG_IMX21_IMX27_UART depends on the non-existing config
SOC_IMX21.
