Update NFC INT wait timeout value to 1s.
1s should be enough for all platforms.
If INT bit not set for 1s timeout value, this
should be high potential of IC issues.

Do not disable the eSDHC clk on MX35 3DS board,
since SYSTEM can't boot up after the reset key
is pressed when the SD/MMC boot mode is used.
The root cause is that the ROM code don't ensure
the SD/MMC clk is running when boot system.

add dmfc size control for dynamic change and _setup.
DMFC_NORMAL: segment 0,1 for DC, 4,5 for DP-BG, 6,7 for DP-FG.
DMFC_HIGH_RESOLUTION_DC: segment 0~3 for DC, 4,5 for DP-BG, 6,7 for DP-FG.
DMFC_HIGH_RESOLUTION_DP: segment 0,1 for DC, 2~5 for DP-BG, 6,7 for DP-FG.
DMFC_HIGH_RESOLUTION_ONLY_DP: segment 0~3 for DP-BG, 4~7 for DP-FG.
IPU diplay driver will try to enlarge its related DMFC segment size
when it meet high resolution condition, but if dmfc is already in high
resolution setting, dmfc will not change.That said, first request wins.
For cmdline setting, "dmfc=1" is DMFC_HIGH_RESOLUTION_DC, "dmfc=2"
is DMFC_HIGH_RESOLUTION_DP, "dmfc=3" is
DMFC_HIGH_RESOLUTION_ONLY_DP.
NOTE: DMFC_HIGH_RESOLUTION_ONLY_DP only can be set by cmdline.

The unexpected messages are printed by the kernel.
The root cause is that the I2C IO func can't be called in the
interrupt context, since the SD/MMC port and CD PIN is logically
walk through the MCU I2C bus.
Solution:Don't call the I2C IO func in the interrupt context in
card detection IRQ handler, move them to work-queue enviroment.
