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

1In the scenario of active waiting, context switching is inevitable, and we can eliminate redundant judgments.

Summary
The original implement for exception handler is very simple and
haven't framework for breakpoint/watchpoint routine or brk instruction.
I refine the fatal handler and add framework for debug handler to
register or unregister. this is a prepare for watchpoint/breakpoint

Stack and backtrace dump for Espressif's SoCs (ESP32, ESP32-S2,
ESP32-S3, ESP32-C3, ESP32-C6 and ESP32-H2) is now documented in a
new section for each chip entry page.
The script can decode the backtrace dump, considering the syntax
of the backtrace format (properly handle the dump when SMP is
enabled, for instance) based on chip name or the toolchains's
addr2line tool.
- Fix `MAKE_PC_FROM_RA` macro to consider the instruction region
base address;
- Add sanity check for calculated PC and SP registers;
- Check if the stack pointer is within the interrupt stack to
enable backtrace dump if an exception occurs during the ISR;
`CONFIG_XTENSA_INTBACKTRACE` is necessary to enable backtrace dump
for the tasks because exceptions are treated like interrupts (even
when an exception occurs during a normal task execution). It's now
automatically selected when `CONFIG_SCHED_BACKTRACE` is enabled.
This commit also removes outdated Kconfig options.
