69ed5bb67d Various fixes for PCI work
Squashed commits:

1. Porting prior PCI work in place of jailhouse code

At this point the PCI enumeration works for x86_64 including over
pci-pci bridges.

Running QEMU with this configuration we see the bridge and the
device on the bridge.  It also detected the qemu test device

1349dcfc1f drivers/usbhost: Add a USB bluetooth driver.
This change adds support for the USB Transport Layer as described
in the bluetooth spec. Isochronous endpoints are not yet supported.
Because of limitations in the NuttX bluetooth stack, only one USB
device can be used. This driver will only allow one USB dongle to
use bluetooth.

A Laird USB BT4.2 dongle (from Mouser) was used for testing:
M/N BT851 1.0 1829, FCC ID:SQGBT850
lsusb: 04b4:f901 Cypress Semiconductor Corp. CYW20704A2

The following commands were used to test from the nsh prompt:
bt bnep0 scan start
bt bnep0 scan stop
bt bnep0 scan get
bt bnep0 info

The Linux gatttool was used to connect over wireless.

With the BDAddr found by "bt bnep0 info", start gatttool using:
gatttool -b BDAddr -I

Connect to the device using:
connect

Read the device name using the GAP device name UUID:
char-read-uuid 2a00

Part of the response is:
value: 41 70 61 63 68 65 20 4e 75 74 74 58
which is the string "Apache NuttX"

c479ccb8aa sched: move etc romfs mount from nsh to sched/init
Usually the startup script is placed under /etc. The contents of the etc directory
are compiled and linked with Nuttx binary in the form of romfs. After startup,
it will be  mounted by Nsh.

etc is generated by the different boards, that use genromfs and xxd tools to generate
and compile it into the Nuttx, for example: boards/arm/at32/at32f437-mini/tool/mkromfs.sh
The more common method is etc image generated from the content in the corresponding
board/arch/board/board/src/etc directory, and added by Makefile for example:
boards/sim/sim/sim/src/etc.

But in kernel/protected mode, Nuttx kernel and apps are run in different privileged/
non-privileged mode or the isolated binarys, so as that nsh should use syscall to
access Nuttx kernel by exported API. In this scenario, nsh can not mount the etc image
content, because that is generated in board and as a part of Nuttx kernel.

changes:

- move etc romfs mount from nsh to Nuttx, but keep the script to parse and execute.
- move and rename the related CONFIG, move customized nsh_romfsimg.h to etc_romfs.c
  in boards, and no need declaration for romfs_img/romfs_img_len.

This commit changes and updates all configurations in Nuttx arch/board as much as possible,
but if any missing, please refer to the following simple guide:

- rename CONFIG_NSH_ROMFSETC to CONFIG_ETC_ROMFS, and delete CONFIG_NSH_ARCHROMFS in defconfig
- rename the etc romfs mount configs, for example CONFIG_NSH_FATDEVNO to CONFIG_ETC_FATDEVNO
- move customized nsh_romfsimg.h to etc_romfs.c in board/arch/board/board/src and no need
  declaration for romfs_img/romfs_img_len.
- delete default nsh_romfsimg.h, if ROMFSETC is enabled, should generate and compile etc_romfs.c
  in board/arch/board/board/src.

996625ec58 riscv/arch_elf.c: Handle PCREL_HI20/LO12_I/S relocations correctly
There is a problem with the current elf loader for risc-v: when a pair of
PCREL_HI20 / LO12 relocations are encountered, it is assumed that these
will follow each other immediately, as follows:

label:
	auipc      a0, %pcrel_hi(symbol)    // R_RISCV_PCREL_HI20
	load/store a0, %pcrel_lo(label)(a0) // R_RISCV_PCREL_LO12_I/S

With this assumption, the hi/lo relocations are both done when a hi20
relocation entry is encountered, first to the current instruction (addr)
and to the next instruction (addr + 4).

However, this assumption is wrong. There is nothing in the elf relocation
specification[1] that mandates this. Thus, the hi/lo relocation always
needs to first fixup the hi-part, and when the lo-part is encountered, it
needs to find the corresponding hi relocation entry, via the given "label".
This necessitates (re-)visiting the relocation entries for the current
section as well as looking for "label" in the symbol table.

The NuttX elf loader does not allow such operations to be done in the
machine specific part, so this patch fixes the relocation issue by
introducing an architecture specific cache for the hi20 relocation and
symbol table entries. When a lo12 relocation is encountered, the cache
can be consulted to find the hi20 part.
