This fixes the always zero time in NuttSBI case as the `error` field
contains the correct timestamp. This in turn also fixes the block of
`up_udelay()` which further leads to boot failure of `canmv230:master`
config.

Correctly releasing channels after using QSPI is crucial
to prevent issues caused by multiple requests that may lead
to DMA channel resource conflicts.
The common `up_allocate_heap` is a strong symbol, which leads to
error when building with CONFIG_DEBUG_LINK_WHOLE_ARCHIVE. Make
`up_allocate_heap` weak function to mitigate this problem.

This PR configures the BL808 and SG2000 MMU (inside T-Head C906) to cache the the Kernel Text, Data and Heap. We set the MMU Flags (Shareable, Bufferable and Cacheable) as explained in this article: https://lupyuen.github.io/articles/plic3#appendix-mmu-caching-for-t-head-c906
This PR fixes the Slow Memory Access for NuttX Kernel in BL808 and SG2000: https://github.com/apache/nuttx/issues/12696
In the next PR, we will fix the Slow Memory Access for NuttX Apps, by caching the User Text and Data.
arch/risc-v/src/bl808/bl808_mm_init.c: Added MMU Flags (Shareable, Bufferable and Cacheable) for BL808 Kernel Text, Data and Heap

This fixes `tp` value of forked child in PROTECTED build to support
vfork. Why? the optimized `dispatch_syscall` requires `tp` to hold
the task TCB since commit e6973c764c.

Larger RX/TX buffers might be required for both FD and FD_BSW modes.
Default bit timing values are also changed since the original ones
did not provide correct results for default SAMv7 board clock selection
(150 MHz clock frequency). The current values provide correct bit timing
with sample point as close to 87.5 %.

This adds field type to canioc_bittiming_s structure that allows
to set/obtain bit timing for both CAN CC and CAN FD.
CANIOC_GET_BITTIMING is now bidirectional: user specifies type field
and gets other fields from the controller.
The commit also updates current CAN FD capable controllers using the
ioctl. The type is not checked for classical CAN only controllers
and nominal bit timing is returned regardless of type value.

This adds enablers for setting various clocks to some default
values. Also, this provides helpers to grant nonsecure access
to a number of clocks. Bootloader may utilize these to make
the system boot in a deterministic manner.
