Subject: [PATCH v2 2/2] hwspinlock: qcom: Remove IPQ6018 SOC specific compatible

IPQ6018 has 32 tcsr_mutex hwlock registers with stride 0x1000.
The compatible string qcom,ipq6018-tcsr-mutex is mapped to
of_msm8226_tcsr_mutex which has 32 locks configured with stride of 0x80
and doesn't match the HW present in IPQ6018.

Remove IPQ6018 specific compatible string so that it fallsback to
of_tcsr_mutex data which maps to the correct configuration for IPQ6018.

Changes in v2:
 - Updated commit message
 - Added Fixes and stable tags

Cc: stable@...r.kernel.org
Fixes: 5d4753f741d8 ("hwspinlock: qcom: add support for MMIO on older SoCs")
