mfd: exynos-lpass: Fix an error handling path in exynos_lpass_probe()
[ Upstream commit 484f0f59f09edd1f6fa63703c12eb30d72a519ac ]
If an error occurs after a successful regmap_init_mmio(), regmap_exit()
should be called as already done in the .remove() function.
Switch to devm_regmap_init_mmio() to avoid the leak and simplify the
.remove() function.
Fixes: c414df12bdf7 ("mfd: exynos-lpass: Add missing remove() function")
