ipmi: kcs_bmc: Add a "raw" character device interface

The existing IPMI chardev encodes IPMI behaviours as the name suggests.
However, KCS devices are useful beyond IPMI (or keyboards), as they
provide a means to generate IRQs and exchange arbitrary data between a
BMC and its host system.

Implement a "raw" KCS character device that exposes the IDR, ODR and STR
registers to userspace via read() and write() implemented on a character
device:

+--------+--------+---------+
| Offset | read() | write() |
+--------+--------+---------+
| 0 | IDR | ODR |
+--------+--------+---------+
| 1 | STR | STR |
+--------+--------+---------+

This interface allows userspace to implement arbitrary (though somewhat
inefficient) protocols for exchanging information between a BMC and host
firmware. Conceptually the KCS interface can be used as an out-of-band
mechanism for interrupt-signaled control messages while bulk data
transfers occur over more appropriate interfaces between the BMC and the
host (which may lack their own interrupt mechanism, e.g. LPC FW cycles).

poll() is provided, which will wait for IBF or OBE conditions for data
reads and writes respectively. Reads of STR on its own never blocks,
though accessing both offsets in the one system call may block if the
data registers are not ready.

ipmi: ASPEED_BT_IPMI_BMC: select REGMAP_MMIO instead of depending on it

REGMAP is a hidden (not user visible) symbol. Users cannot set it
directly thru "make *config", so drivers should select it instead of
depending on it if they need it.

Consistently using "select" or "depends on" can also help reduce
Kconfig circular dependency issues.

Therefore, change the use of "depends on REGMAP_MMIO" to
"select REGMAP_MMIO", which will also set REGMAP.
