Sometimes we want to display logo at hdmi screen. but hdmi uboot
resolution maybe different with framebuffer size, so we need read
logo config from regs and decide how to display logo at kernel.
now only support uboot logo size = kernel logo size

There are two thread will update the win config,
one is update_regs handler, another is hdmi hotplug
thread, win config maybe modify by another thread
unexpectly, then vop scan umap address, cause iommu
crash, so we need use a mutex to protect win config.

dw_mci write cmd index to CMD register to trigger sending cmd by BIU.
However, if device fall into panic holding cmd/data line to low level cause BIU
cannnot send out cmd forever. So no cmd_done_int will come. AND, cmd response timeout
only valid after cmd been sent. Nothing to break this loop, we need a s/w recovery from
STATE_SENDING_CMD to STATE_IDLE, and the pending one reported as -ETIMEOUT, let caller
decide howto again.

For box, we need to set hdmi switch state when insert/remove,
regardless of whether the device supports audio. So add function
rk_fb_get_display_policy() to get display policy.
Read block device partition table from command line. The partition used
for fixed block device (eMMC) embedded device. It is no MBR, save
storage space. Bootloader can be easily accessed by absolute address of
data on the block device. Users can easily change the partition.
