misc: ibmasm: Remove obsolete IBM Remote Supervisor Adapter driver

The IBM Remote Supervisor Adapter (RSA) and RSA II were out-of-band
management PCI/ISA cards introduced in the early 2000s for ancient
IBM eServer xSeries machines. IBM deprecated the RSA family and
replaced it with the Integrated Management Module (IMM) around 2008.
IBM subsequently sold its x86 server business to Lenovo in 2014, and
modern systems use entirely different BMC architectures.

This hardware has been completely obsolete and out of production for
over 15 years. Surviving physical servers using this specific hardware
would be running ancient 32-bit processors vastly unsuited for modern
kernels.

A review of the recent git history shows that aside from mechanical
treewide VFS API updates, the only recent activities are out-of-bounds
fixes in command_file_write and MFA handling. These fixes address
userspace-triggered security vulnerabilities and fuzzer-discovered
MMIO bugs rather than functional issues reported by active hardware users.

Keeping this obsolete driver in the tree leaves an unnecessary attack
surface and acts as a "fuzzing honeypot", forcing core maintainers to
endlessly review CVEs and OOB fixes for dead hardware, while also paying
a maintenance tax to drag it through modern API refactorings.

Remove the driver entirely.
