arm: tegra: enterprise: use proper backlight clk_div for A03/A04tegra-l4t-r15-betategra-l4t-er-2012-04-02
The new TPS61160A part asks for the control PWM signal to be between 5kHZ and 100kHz. This change sets clk_div to 0x1D for a 5kHz signal. This change also installs a linear table for enterprise_bl_output_measured_a03.
