tty: serial: samsung: set UPIO_MEM32 iotype for gs101

GS101's Connectivity Peripheral blocks (peric0/1 blocks) which
include the I3C and USI (I2C, SPI, UART) only allow 32-bit
register accesses.

Instead of specifying the reg-io-width = 4 everywhere, for each node,
the requirement should be deduced from the compatible.

Infer UPIO_MEM32 iotype from the "google,gs101-uart" compatible.
Update the uart info name to be GS101 specific in order to
differentiate from the other exynos platforms. All the other settings
are not changed.

exynos_fifoszdt_serial_drv_data was replaced by gs101_serial_drv_data
because the iotype restriction is gs101 specific and there was no other
user of exynos_fifoszdt_serial_drv_data.
