Subject: [PATCH v2] tty: serial: samsung: Improve naming for common macro

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. While at it,
also convert .has_usi field type to bool, so its usage is more obvious.

Signed-off-by: Sam Protsenko <semen.protsenko@...aro.org>

Changes in v2:
  - Converted .has_usi field to boolean
  - Used true/false instead of 1/0 values in
    EXYNOS_COMMON_SERIAL_DRV_DATA() macro
