firmware: correct the get_cursor() argument types

We only ever pass uint8_t * to get_cursor(), so update the prototypes
and fix the following compiler warnings,

In function ‘__ansicon_open’:
com32/lib/sys/ansicon_write.c:93:6: warning: passing argument 1 of ‘firmware->o_ops->get_cursor’ from incompatible pointer type [enabled by default]
com32/lib/sys/ansicon_write.c:93:6: note: expected ‘int *’ but argument is of type ‘uint8_t *’
com32/lib/sys/ansicon_write.c:93:6: warning: passing argument 2 of ‘firmware->o_ops->get_cursor’ from incompatible pointer type [enabled by default]
com32/lib/sys/ansicon_write.c:93:6: note: expected ‘int *’ but argument is of type ‘uint8_t *’
