lib: sbi: Add timer frequency to struct sbi_timer_device
Generic mdelay() and udelay() functions can be provided by the
sbi_timer framework if timer frequency is available in the timer
instance provided by the platform support or timer driver.
This patch adds timer frequency (timer_freq) member in the
struct sbi_timer_device for above purpose.
