[ Upstream commit b4a2adbf3586efa12fe78b9dec047423e01f3010 ]

Older gcc versions get confused by comparing a u32 value to a negative constant in a switch()/case block:

drivers/clk/tegra/clk-tegra20.c: In function 'tegra20_clk_measure_input_freq': drivers/clk/tegra/clk-tegra20.c:581:2: error: case label does not reduce to an integer constant case OSC_CTRL_OSC_FREQ_12MHZ: ^~~~ drivers/clk/tegra/clk-tegra20.c:593:2: error: case label does not reduce to an integer constant case OSC_CTRL_OSC_FREQ_26MHZ:

Make the constants unsigned instead.
