bmp388 works poorly as the system fires STOPs even in
a beginning of a transaction. Don't let unrelated STOPs
to distort the data flow.

This adds 2 more FPGA I2Cs. Also rework the indexing
so that it matches the earlier work without major changes.

This fixes the following issue:
- After sending the address, the driver writes an extra zero
Without this patch, the extra write causes an extra ACK that would
terminate the sequence prematurely. This is observed as data read
corruption.
With this fix, the condition is detected precisely. That being the
case, the sequence is continued with a repeated start, after which
the read continues normally.

This incorporates an fpga i2c driver into the existing i2c driver.
This fpga i2c works almost 100% as the MSS i2c, but the difference
is that the fpga driver terminates all transactions with a stop
sent -interrupt. That needs to be handled.
Fpga clock source is also different, act accordingly.
SEC2TICK(10) is an overkill to any app, use just one second instead.
modifyreg32s are simplified as well, no need to clear and set
as set is enough.

I2C status register reset value (0xf8) was not handled properly causing unnecessary bus resets.
Added critical section to mpfs_i2c_reset() and removed unnecessary interrupt disabling elsewhere.
Problem:
When tcp_close_work starts to run in LPWORK, if another event comes and
calls tcp_free before tcp_close_work takes net_lock, the tcp_free will
be called twice and cause double free.

Board related code may use different mounts for MTD device (block
character for one, SmartFS for another) if required by the board.
Additional type member was therefore added to mtd_partition_s structure
in order to support this.

Confirmation of the IN request must be done immediately after all data has been transferred,
otherwise sending data when more than one request has been added to the queue will
not work properly.
This is a refactored version of the SLIP network driver. Updates
include:
1. The original design started two kernel threads per SLIP device.
The refactored version uses file_poll to essentially be driven
by the UART RX and TX interrupts and pushes work to the low
priority work queue.
2. The SLIP byte un-/stuffing is more efficient now, using memcpy
instead of handling each byte individually.
3. The switch of the old SLIP driver to IOBs caused buffer overwrites
if packets were sent that would not fit into a single IOB. This is
fixed now.

The following changes make it possible for Nuttx to load binaries in ELF format which are fully linked.
The change does not include the necessary modifications to produce such binaries. In order to build an applicable binary:
- The userspace applications linker script (`gnu-elf.ld`) needs to modified so the data and text section origin's match those setup by the address environment.
- The makefile used, in `apps/import/Make.defs` needs to remove the `-r` LDELFFLAG.
