wireless-regdb: Raise DFS TX power limit to 250 mW (24 dBm) for the US

According to 47 CFR § 15.407(a)(2), the U-NII-2A (5.25-5.35 GHz) and
U-NII-2C (5.47-5.725 GHz) DFS bands are subject to the following [1]:
"For the 5.25-5.35 GHz and 5.47-5.725 GHz bands, the maximum conducted
 output power over the frequency bands of operation shall not exceed
 the lesser of 250 mW or 11 dBm + 10 log B, where B is the 26 dB
 emission bandwidth in megahertz."

As such, increase the TX power limit for the U-NII-2A and U-NII-2C DFS
bands to 250 mW (24 dBm) to match the FCC's current rules. These power
limits have remained unchanged since the § 15.407 amendment by the FCC
in 2014 [2].
