pwm: tegra: Fix 32 bit build
The value of NSEC_PER_SEC << PWM_DUTY_WIDTH doesn't fix within a 32 bit
integer causing a build warning/error (and the value truncated):
drivers/pwm/pwm-tegra.c: In function ‘tegra_pwm_config’:
drivers/pwm/pwm-tegra.c:148:53: error: result of ‘1000000000 << 8’ requires 39 bits to represent, but ‘long int’ only has 32 bits [-Werror=shift-overflow=]
148 | required_clk_rate = DIV_ROUND_UP_ULL(NSEC_PER_SEC << PWM_DUTY_WIDTH,
| ^~
Explicitly cast to a u64 to ensure the correct result.
Fixes: cfcb68817fb3 ("pwm: tegra: Improve required rate calculation")
