clk: tegra20: fix gcc-7 constant overflow warning
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.
