drivers: i2c_bitbang: Do not use CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC
On some SoCs the frequency of the system clock is obtained at run time as the exact configuration of the hardware is not known at compile time. On such platforms using CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC define directly introduces timing errors. This commit replaces CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC by the call to inline function sys_clock_hw_cycles_per_sec() which always returns correct frequency of the system clock.

drivers: i2c_cc32xx: Get clock frequency from DTS
The i2c_cc32xx driver used system clock frequency as a base for I2C clock frequency calculation. This commit corrects that by obtaining the needed value from DTS. Please note, that for I2C devices the clock-frequency property specifies SCK frequency, instead of frequency of the clock driving peripheral. To solve that problem, a new property was added.
