tty/8250_early: Don't truncate last character of options
The earlier change to use strlcpy uncovered a bug in the options argument length calculation causing last character to be truncated. This makes the actual console to be configured with incorrect baudrate when specifying the console using console=uart,... syntax. Bug symptom seen in kernel log output: Kernel command line: console=uart,mmio,0x90000000,115200 Early serial console at MMIO 0x90000000 (options '11520') which then results in a invalid baud rate 11520 instead of the expected 115200 when the console is switched to ttyS0 later in the boot process.
