George Stark 132fe6c1ee pwm: meson: Use mul_u64_u64_div_u64() for frequency calculating 
[ Upstream commit 32c44e1fa9 ]

While calculating frequency for the given period u64 numbers are
multiplied before division what can lead to overflow in theory so use
secure mul_u64_u64_div_u64() which handles overflow correctly.

Fixes: 329db102a2 ("pwm: meson: make full use of common clock framework")
