This patch will do the following:
1. For mlb will not be able to know whether the final package is
completely sent, add a delay for final package to be sent.
2. Adjust MLB's iram buffer usage. Old code will add addtional
usage of iram buffer.
3. Code format change.
4. In resume function, calling init function after clock is enabled.

In testing async mode on mx6q ard and mx6dl ard, driver always said "can
not alloc rx buffer".
Change async's ring buffer size from 2048 to 1536(MEP package size) and
reduce the extra ring buffer for drop package, now the iram usage amount
in async mode reduced from 34816 to 24576.

Use circle buf to replace old ringbuf mechanism.
Change to use circle buffer in read, write, rx isr and tx isr functions.
In first design of MLB, it's using it's own mechanism to manage ring
buffer, like in mxc_mlb.c.
And then, I saw that kernel already had a serials of circ buffer macros
which can be used to manage ring buffers.
This patch is to use circle buffer macros to manage mlb internal ring
buffers.
For detail of circle buffers, you can refer to
linux-2.6-imx/Documentation/circular-buffers.txt.

Reset whole CDR in init function. This will make mlb connection to MITB
more stable.
This is a missed part in mx6 rm's mlb section, but new in mlb's latest
spec DS62420AP2.pdf 12.1.1-1.
Without this patch, mlb may receive irq from MITB during initialization.
It might cause some connection issue that mlb can't receive data
sometimes. It was treat to be MITB's fault before we get the latest
spec.
