pow(2, aon_clk_div) can be replaced with (1 << aon_clk_div) to eliminate the need to include <math.h>. Signed-off-by: Tahsin Mutlugun <[email protected]>

Description
Since
aon_clk_divis an integer,pow(2, aon_clk_div)can be replaced with(1 << aon_clk_div)inMXC_UART_SetFrequency. This eliminates the need to include <math.h> in UART driver.Motive
Zephyr uses its own math library which provides an implementation of
pow(). When running batch tests, however, it switches to a minimal implementation of the C library that does not include thepow()function. As a result, UART drivers cannot be compiled and tests fail.Checklist Before Requesting Review
