The main functionality of this info function is available via the existing
micropython.mem_info() and micropython.qstr_info() functions. The printing
of the address space layout doesn't add much and removing esp.info() saves
about 600 bytes.

The ones that are moved out of iRAM should not need to be there, because
either they call functions in iROM (eg mp_hal_stdout_tx_str), or they are
only ever called from a function in iROM and not from an interrupt (eg
ets_esf_free_bufs).
This frees up about 800 bytes of iRAM.
It was originally in IRAM due to the linker script specification, but
since the function moved from lib/utils/interrupt_char.c to py/scheduler.c
it needs to be put back in IRAM.
The specific board can be selected with the BOARD makefile variable. This
defaults (if not specified) to BOARD=GENERIC, which is the original default
firmware build. For the 512k target use BOARD=GENERIC_512K.
