Copy the best rational approximation calculation routines from Linux.
Typical usecase for these routines is to calculate the M/N divider
values for PLLs to reach a specific clock rate.

UPSTREAM: lib: Add hexdump

Often during debugging session it's very interesting to see
what data we were dealing with. For example what we write or read
to/from memory or peripherals.

This change introduces functions that allow to dump binary

print_hex_dump_bytes("", DUMP_PREFIX_OFFSET, buf, len);
------------------->8----------------

which gives us the following:

lib: introduce bidram for GD board bi_dram[] memory management

Some platform provides more than one dram banks and reserved firmware
regions (eg. ATF, OP-TEE, etc) by pre-loader dynamically. It means
there are memory holes in board dram layout. What's more, U-Boot will
reserved regions at the late bootflow(eg. firmware reserved for AMP).

So we introduce bidram mechanism to manage GD board bi_dram[], which
provides a way to easily manage memory holes and update bi_dram[]. It
dpends on LMB which provides a good algorithm to manage memory blocks.

What's different from sysmem?
- bidram manage and pass the avaliable memory blocks to kernel;
- sysmem is only for U-Boot memory management to avoid ram overlap,
it doesn't matter about kernel avaliable memory.

lib: introduce sysmem for permanent memory management

U-Boot provides MALLOC for runtime temporary memory management and
LMB for bootm memory management. There is not a mechanism for permanent
memory management. so that the memory blocks are easy to overlap with
each other.

What does permanent memory mean ?
- The memory can't be touched by U-Boot(ATF/OPTEE/SHM/kernel-reserved, etc);
- The memory occupied even in kernel, such as some firmware load buffer;

This patch introduces sysmem to do permanent memory management, which
implements base on LMB. It provides memory block (pool):
- init;
- add;
- alloc;
- free;
- reserve;
- stat;
- overflow check;

Here is an example for RK3399 sysmem boot stat(assume the "fdt" region is Overflow)
