[PATCH] iio: adc: ad7625: fix type mismatch in clamp() macro

[Giorgi Tchankvetadze]

Smatch reports a type mismatch warning in ad7625_set_sampling_freq()
where the clamp() macro is evaluating differing types:
- `target` is a u32
- `100` evaluates as a signed int
- `10 * KILO` evaluates as an unsigned long (due to KILO being 1000UL)

Replace clamp() with clamp_t(u32, ...) to explicitly cast the bounds
to match the u32 target variable.
