Steven Price 3082f8705e pwm: tegra: Fix 32 bit build
[ Upstream commit dd1f1da4ad ]

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.
