On S2 the brown out detector would occasionally trigger erroneously during deep sleep.
Disable it before sleeping to circumvent this issue.

Sometimes the flash size read from bootloader is not correct. This may
forbid SPI Flash driver from reading the the area larger than the size
in bootloader header.
When the new config option is enabled, the latest configured
ESPTOOLPY_FLAHSIZE in the app header will be used to override the value
read from bootloader header.
Added BD_ADDR comparison in l2cu_lcp_allocate and removed check from
security connection request handler as it's handled in l2cu_lcp_allocate
for both connection request and create connection.
There was no need for this function as there is already a way present to
fetch own mac address. Own mac addr can be fetched by calling
controller_get_interface().
With the introduction of cookies to track a session, it is possible that the
clients restart the provisioning on the same session, specifically when a user
cancels a current provisioning attempt. This can result in an error as the state
on the device side and client side will go out of sync.
This has now been changed such that if SESSION_STATE_CMD0 is received on
an existing session, the state is reset and flow allowed to continue.
Earlier, a "socket connection" was being considered as a protocomm "session".
However, for HTTP, we cannot expect clients to necessarily use the same
socket for all requests of a given transaction. This was indeed causing
some failures for Wi-Fi provisioning from Android phones.
So, we have introduced http cookies to track a session even if the socket
connection does not stay intact throughout the transaction.
This change is backward compatible. If the client does not use cookies, the
socket connection will be considered as the session.

Not necessary in these cases, and prevents parens from expanding into the
assembly code added in the parent commit - a pattern which is accepted
by GCC assembler but illegal syntax for LLVM assembler.
Fix for issues where RTC FAST memory is updated as part of going into deep
sleep. Very high risk if heaps are in RTC memory - in particular task stacks
may be in RTC memory, but also other variables.
Also fixes potential concurrency problems as RTC FAST memory is not accessible
by CPU during the CRC calculation itself.
Method:
- Disable interrupts (currently for single core only, will need update for S3)
- Load all registers before calculating CRC or going to sleep
