We do not make use of rust support in the kernel and there
are still some unresolved issues with host leakage when
rust support is enabled, so disable for now.

The current config is in pretty rough shape, missing lots of
useful core features. This is a first step at improving the
situation.
Enable useful core features:
- hrtimer
- tickless idle
- CPU idle
- CPU frequency scaling
- RTC
- low overhead hardening options
- BPF JIT
Enable common storage options:
- SATA
- NVMe
Enable drivers for commonly found hardware:
- Realtek PCI(e) ethernet
- USB (oHCI, eHCI, xHCI)

v4: disable INITRAMFS_PRESERVE_MTIME
v3: enable BLK_DEV_SD for proper USB storage support

The new x86_64 kernel configuration prefers ZSTD over LZOP
for better compression performance.

Most new projects require initrd support, so we want all reference
configs maintained in this repo to enable the kernel support.
This override can be removed once upstream reason ceases to enforce
initrd support to be disabled.

Most updates since the last review of the kernel config
were done by accepting the defaults for newer kernel
versions, which may not always align with what we want
as our kernel config in this BSP.
The general ideas motivating the changes are:
- don't enable core features or workarounds for CPUs
that are not present on any of the supported SoCs
in the BSP
- disable drivers for peripherals that aren't found
on any of the supported boards in the BSP
- enable drivers for peripherals present on supported
boards or SoCs (this is best effort and has not been
checked exhaustively)
- enable hardening options when they are deemed to be
unlikely to have a substancial negative impact on
performance
