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.

Commit 5d4753f741 ("hwspinlock: qcom: add support for MMIO on older
SoCs") introduced and made regmap_config mandatory in the of_data struct
but didn't add the regmap_config for sfpb based devices.
SFPB based devices can both use the legacy syscon way to probe or the
new MMIO way and currently device that use the MMIO way are broken as
they lack the definition of the now required regmap_config and always
return -EINVAL (and indirectly makes fail probing everything that
depends on it, smem, nandc with smem-parser...)
Fix this by correctly adding the missing regmap_config and restore
function of hwspinlock on SFPB based devices with MMIO implementation.

msb of the regmap_field was mistakenly given the value 32, to set all bits
in the regmap update mask; although incorrect this worked until 921cc294,
where the mask calculation was corrected.
