arm: armv7: solve issue for timer_rate_hz in arch timer
The current value timer_rate_hz causes a problem with function timer_get_us() from lib time and then an issue with readx_poll_timeout() function. With corrected value for tbclk() = timer_rate_hz = CONFIG_SYS_HZ_CLOCK the weak functions in lib timer can be used: - get_timer() - __udelay() So the specific function in this file are removed.
