Subject: [PATCH v3 1/8] tty: serial: samsung: embed s3c24xx_uart_info in parent structure

Embed "struct s3c24xx_uart_info" directly as a member of "struct
s3c24xx_serial_drv_data" instead of keeping it as a pointer.  This makes
the code clearer (obvious ownership of "struct s3c24xx_serial_drv_data")
and saves one pointer.
