IPQ6018 has 32 tcsr_mutex hwlock registers of 0x1000 size each.
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.

This series fixes the following:
 1. Fix the tcsr_mutex register size to 0x20000 in IPQ6018 DTSI.
 2. Remove IPQ6018 specific compatible in hwspinlock driver so that it
    falls back to pick of_tcsr_mutex data.

Changes in v2:
 - Drop changes to remove qcom,ipq6018-tcsr-mutex from dt-bindings
 - Drop changes to remove qcom,ipq6018-tcsr-mutex compatible from
   ipq6018.dtsi
 - Add Fixes and stable tags

IPQ6018's TCSR Mutex HW lock register has 32 locks of size 4KB each.
Total size of the TCSR Mutex registers is 128KB.

Fix size of the tcsr_mutex hwlock register to 0x20000.

 - Drop change to remove qcom,ipq6018-tcsr-mutex compatible string
 - Added Fixes and stable tags

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

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