OMAPDSS: DSI: Fix bug when calculating LP command interleaving parameters
In function dsi_compute_interleave_lp(), the escape clock/LP clock time period
is calculated incorrectly. The escape clock/LP clock is calculated as:
LP Clock(Hz) = DSI_FCLK(Hz) / lp_clk_div
Since we are calculating the time period of LP clock, the LP clock divider
should be multiplied with the time period of DSI_FCLK.
Calculating incorrect value of txclkesc results in incorrect calculation of LP
interleaving parameters, it also creates a possibility of a divide by zero
error.
