This is a tool for associating discrete IDs with addresses.
This tool is implemented through the red-black tree method provided by <sys/tree.h>, and the time complexity when calling, searching, and deleting is optimized to O(logn)
The implementation is the moving node operation of two red-black trees
1. When applying for a node, it will first check whether there is an available node in the "removed" tree. If so, the memory address of the node will be reused and moved to the "alloced" tree.
2. If the "removed" tree is an "empty tree", then the node will be requested from the memory and added to the "alloced" tree
3. Similarly, when removing a node, we set the address pointed to in the node to "NULL" and move it to the "removed" tree. Next time we alloc the node, we can reduce the overhead caused by memory application
For now, we still have something that can be optimized, and that is the memory elimination mechanism of the "removed tree". The current implementation will only release all the content under the "removed" tree when the idtree is destroyed.

If per tick is set to 10ms, it will cause nxsig_usleep(1000) in the
sdio driver to sleep for 19ms, which is much longer than the
expected 1ms, resulting in very low write performance. Add option to
reduce CPU hogging by using sched_yield(), though it may also affect
write performance when the CPU is busy.

In mmcsd_cardidentify(), the clock is not enabled before issuing
CMD0, and the clock has been disabled in mmcsd_removed(). It makes
no sense to enable the clock after issuing CMD0, because when CMD0
is issued, it will exit with error due to the clock is not enabled.

According to the eMMC specification, in Backwards Compatibility
with legacy MMC card mode, the frequency of the SD clock must be
0-26 MHZ; in high speed SDR mode, it must be 0-52MHZ. So we should
switch to high speed SDR mode if the clock frequency is higher than
26MHZ.
