tty: serial: use module_init on pl011_init
If amba serial driver is probed defer, amba serial driver may be
probed after init process. So the error log shows in below.
[ 0.389403] Warning: unable to open an initial console.
[ 0.390107] Freeing init memory: 2328K
It results in serial console not enabled. So replace arch_initcall
by module_init on pl011_init(). The boot sequence is changed in below.
pinctrl driver --> amba serial driver --> init process
