qualcommax: ipq50xx: fix uniphy soft reset issue

The resets in the GCC of the uniphy found in the IPQ5018 SoC are
incorrect which broke the ability to shift between 1G and 2.5G link
speeds. So let's correct the resets based on below two downstream
commits.

In a seperate and prequisite PR to the QCA-SSDK repo, logic has been
implemented to select the right reset based on the link setup so fixed
link scenarios don't break.

+Subject: [PATCH] clk: qcom: gcc-ipq5018: fix UNIPHY soft reset issue
+
+The SOFT reset is supposed to trigger a resets across the SYS, RX, and
+TX lines of the IPQ5018 UNIPHY. So let's set the bitmask of the reset
+definition accordingly in the GCC as per the downstream driver.
