Store the rx virtqueue idx to the local headrx index, and only
process the data when the rx virtqueue has data to avoid access
the ram in low power mode.

Previously, address 0x03b70000u was written with shift bits
that only changed the bit width, not the mode. HS mode is
changed via 0x03B90100, which is required, according to Jedec
specs, for DDR mode. HS mode was not applied before. Enforce
DDR mode (50 MHz) for now.
The real boost, however, comes from removing the DMA limitation
at 0x08xxxxxx address space, which now seems unnecessary.

sendfifo() function need enable BWR_IE before checking if BWE is enabled
to avoid BWE to be activated between the BWE check and BWR interrupt
enabling, which causes the interrupt to be missed and Data Timeout error.

This corrects the setting widebus for SD cards, which was recently broken in 4f7f751d2a.
The if checking the priv->caps, priv->buswidth and IS_MMC has been wrong for
some time. The proper logic is that for MMC only the priv->caps is checked.
For SD card, both priv->caps and priv->buswidth need to be checked.

Summary:
The conn->keeptimer units is decisecond，but its unit is treated as
half-second in the tcp_timer & tcp_get_timeout function.
Therefore conn>keeptimer needs to be divided by 5(DSEC_PER_HSEC)
to match half-second units.

with other functionalities removed.
reason:
by doing this we can reduce context switch time,
When we exit from an interrupt handler, we directly use tcb->xcp.regs
