mfd: exynos-lpass: Fix an error handling path in exynos_lpass_probe()

Browse Source 
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: c414df12bd ("mfd: exynos-lpass: Add missing remove() function")
