From: Patrick Rudolph <patrick.rudolph@9elements.com>

As user land tools currently use /dev/mem to access coreboot tables and
CBMEM, provide a better way by using read-only sysfs attributes.

Unconditionally expose all tables and buffers making future changes in
coreboot possible without modifying a kernel driver.

Changes in v2:
- Add ABI documentation
- Add 0x prefix on hex values
- Remove wrong ioremap hint as found by CI

Changes in v3:
- Use BIN_ATTR_RO
