tcp: fix incorrect ca_state in tail loss probe

On receiving an ACK that covers the loss probe sequence, TLP
immediately sets the congestion state to Open, even though some packets
are not recovered and retransmisssion are on the way.  The later ACks
may trigger a WARN_ON check in step D of tcp_fastretrans_alert(), e.g.,
https://bugzilla.redhat.com/show_bug.cgi?id=989251

The fix is to follow the similar procedure in recovery by calling
tcp_try_keep_open(). The sender switches to Open state if no packets
are retransmissted. Otherwise it goes to Disorder and let subsequent
ACKs move the state to Recovery or Open.

mxc_hdmi: Patch for HDMI detect / EDID issues

Fixed EDID (1920x1080) can be used instead of reading EDID from HDMI (which is still buggy on wandboard)
This is based on:
https://github.com/UDOOboard/Kernel_Unico/commit/acca8e0f260f3de326f535b92d6881a9d360cdb3
https://github.com/UDOOboard/Kernel_Unico/commit/a485030198306baa43c6f6131250cc97b31c7f8f

Kernel configuration has to be adopted to enable this functionality - new variables:
CONFIG_FORCE_HDMI_HP_DETECT - Force the presence of an attached HDMI Panel Regardless of the signal present in hpdetect pin.
CONFIG_FORCE_HDMI_FIXED_EDID - Force on-chip MXC HDMI controller to adopt EDID read from external file or static internal kernel table.
