iio: adc: stm32: fix minimum sampling time values

Browse Source 
- On stm32mp15: vddcpu and vddq_ddr are not connected to internal
channel, so their sampling time shouldn't be set.

- On stm32mp13: vddcpu and vddq_ddr are connected to internal channels
and the value for vddcore was not correct. Values from the datasheet
are 1us (e.g. 1000ns) for ts_vddcore, ts_vddcpu and ts_vddq_ddr.

Fixes: 7cb2303dd0 ("iio: adc: stm32: manage min sampling time on all internal channels")
