Having "_USI" suffix in EXYNOS_COMMON_SERIAL_DRV_DATA_USI() macro is confusing. Rename it to just EXYNOS_COMMON_SERIAL_DRV_DATA() and provide USI registers availability for all Exynos variants instead.

Makes sense, although I would prefer to have here true or false. More obvious. Otherwise "1" looks like counter/number for some property. The has_usi field in struct could be then also converted to bool.
