Message-Id: <20220122195731.934494-11-ogabbay@kernel.org>

Subject: [PATCH 11/30] habanalabs: remove asic callback set_pll_profile()
Setting PLL profile is the same for all ASICs, except for GOYA.
However, because this function is never called from common code, there
is no need to have an asic-specific callback function.
