i386: improve the immediate console
Improve the immediate console to the point that it can be enabled and
display e.g. assertion failures from very early on (i.e. from
`c_boot_entry').
* device/cons.h (romgetc, romputc): New declarations.
* i386/configfrag.ac: Add configuration variable.
* i386/i386at/conf.c (dev_name_list): Add entry.
* i386/i386at/cons_conf.c (constab): Add entry.
* i386/i386at/immc.c: Add missing includes.
(immc_cnprobe, immc_cninit, immc_cngetc, immc_romputc): New functions.
(immc_cnputc): Fix signature, use virtual addresses.
* i386/i386at/immc.h: New file.
* i386/i386at/kd.c: Use `#if ENABLE_IMMEDIATE_CONSOLE'.
* i386/i386at/kd.h (kd_setpos): Add missing declaration.
* i386/i386at/model_dep.c (c_boot_entry): Install immediate console as
early boot console.
