From: Anilkumar Kolli <akolli@codeaurora.org>

[ Upstream commit d8792393a783158cbb2c39939cb897dc5e5299b6 ]

Increase pulse width range from 1-2usec to 0-4usec.
During data traffic HW occasionally fails detecting radar pulses,
so that SW cannot get enough radar reports to achieve the success rate.

Tested ath10k hw and fw:
* QCA9888(10.4-3.5.1-00052)
* QCA4019(10.4-3.2.1.1-00017)
* QCA9984(10.4-3.6-00104)
* QCA988X(10.2.4-1.0-00041)

Tested ath9k hw: AR9300
