After the commit b8b541f, the system would not start up properly
with certain coldboot conditions. For example, if the OpenSBI picked
hart4 as the coldboot hart in preference to hart3, the system would
get stuck due to stack corruption. OpenSBI uses a lottery mechanism
to pick the coldboot hart.
Also fix g_scratches area in such a manner than it will not get
initialized to zero. If several harts initialize the area to zero, there's
danger the stack pointer gets wiped out.
Now any coldboot hart works.

Currently the IHC (Inter Hart Communication) depends on OpenAMP and
rptun. However, the bootloader portion of the IHC doesn't need
either of them. Now they are wasting a lot of bootloader space.
Reorganize the bootloader portion into a separate file 'mpfs_ihc_sbi.c'.
This file contains the OpenSBI vendor extensions, or the only required
functionalities for the bootloader. On the other hand, 'mpfs_ihc.c'
contains the non-bootloader code.
This patch also makes it possible to utilize 2 RPMSG channels. This
has been tested so that 2 separate NuttXs on harts 1 and 2 communicate
with Linux kernel that runs on harts 3 and 4.
New configuration files are added as well:
- rpmsg-ch1: sample config for RPMSG
- rpmsg-ch2: sample config for another RPMSG channel
- rpmsg-sbi: sample bootloader config for RPMSG/OpenSBI

If you specify a file path on SPI-Flash in CONFIG_CXD56_GNSS_CEP_FILENAME,
it causes a deadlock issue in the inter-CPU communication. To resolve it,
introduce a new CONFIG_CXD56_GNSS_CEP_ON_SPIFLASH and then use pre-read
buffers during checking CEP file. So this needs the large of free memory.
Remove hardware zero length packet enhancement because of driver
logic already processed the ZLP correctly. It is unnecessary and cause
of IN interrupt lost.
Add initial support for the I2S peripheral on ESP32S2.
Add I2S character driver and generic I2S audio driver.
Include i2schar defconfig for ESP32-S2-Saola-1 board.

In host route mode (bridge mode disabled), the d_pktsize of TAP device is not initialized and will be set to CONFIG_NET_ETH_PKTSIZE in netdev_register, while the MTU on host side keeps at 1500. Input packets larger than CONFIG_NET_ETH_PKTSIZE will be dropped because 'IP packet shorter than length in IP header'.
This patch fix this issue by reading MTU from host side and set as d_pktsize, just the same as what is done in bridge mode.

Share one worker between multiple simulated network devices may work most of the time, but sometimes breaks the tx pipeline when sending packets on more than one interface at the same time, and leaves some packets unprocessed in network stack, delayed until next transmit on the network interface. The rx process is likely delayed in packet processing under similar situation, so keep g_avail_work and g_recv_work the same number as interfaces.

Run-time check for L3 page table size, to ensure it is large enough
to map all of the kernel memory.
NOTE: The check has to be run-time, as KFLASH_SIZE/KSRAM_SIZE are really
linker relocation symbols, and thus cannot be utilized compile-time.
L3 table maps 2MB of memory, this brings an implicit requirement for
any L3 region to be aligned to 2MB. This commit adds build time sanity
checks to ensure this requirement is met.
For other SvXX architectures the boundary requirement (might be) is
different.
