We don't want to claim that we support a serial number string and

string, let's skip setting iSerialNumber to a valid number.

A USB String descriptor can be up to 255 characters long and it's not
NULL terminated according to the USB spec. This means our
MAX_STRING_SERIAL should be 256 (to cope with NULL terminator).

After enabling log printing to lcd, when the screen starts
scrolling, system crashes. Log is shown as bellow:
"Synchronous Abort" handler, esr 0x96000045
"Synchronous Abort" handler, esr 0x96000045
Checking the source code, we found that the variable "pixels"
gets a wrong value:
int pixels = VIDEO_FONT_HEIGHT * vid_priv->line_length;
"pixels" here means the value of pixels for a character, rather
than the bytes for a character. So the variable "pixels" is 4
times bigger than it's exact value, which will cause the memory
overflow when the cpu runs the following code:
for (i = 0; i < pixels; i++)
*dst++ = clr; <<----

sdhci_transfer_data() function transfers the blocks passed up to the
number of blocks defined in mmc_data, but returns immediately once all
the blocks are transferred, even if the loop exit condition is not met
(bit SDHCI_INT_DATA_END set in the STATUS word).
When doing multiple writes to mmc, returning right after the last block
is transferred can cause the write to fail when sending the
MMC_CMD_STOP_TRANSMISSION command right after the
MMC_CMD_WRITE_MULTIPLE_BLOCK command, leaving the mmc driver in an
unconsistent state until reboot. This error was observed in the rpi3
board.
This patch waits for the SDHCI_INT_DATA_END bit to be set even after
sending all the blocks.
