Clean up some x86/mce code as below. No functional changes intended.
  - Simplify some code.
  - Remove some unnecessary code.
  - Improve readability for some code.
  - Convert some family/model mixed checks to VFM-based checks.
  - Fix some typos.

Pass the following basic tests:
  - Tested on an Intel Sapphire Rapids server.
  - Compile test.
  - System boot test.
  - Correctable/uncorrectable memory errors can be notified via CMCI/MCE interrupts.
  - Correctable/uncorrectable memory errors can be dispatched to the mcelog daemon and the EDAC driver.

Changes in v4:
  - Drop the first two patches as they've landed in the TIP ras/core branch.
  - Drop "Make mce_gen_pool_create() return explicit error codes" patch.
  - 0001: Don't rename mce_notify_irq().
  - 0003: New patch. Make four functions return bool.
  - 0004: Add necessary blank lines and directly use 'mca_cfg'.

Changes in v3:
  - Collect "Reviewed-by:" from Nikolay & Sohil.
  - Drop the "x86/mce: Remove the redundant zeroing assignments" patch.
  - 0003: Rename mce_notify_irq() to mce_notify_user().
  - 0005: Move the 'int ret' variable along with the other int variables.
  - 0006: New patch. Break up __mcheck_cpu_apply_quirks().
  - 0007: New patch. Convert family/model mixed checks to VFM-based checks.
  - 0009: Remove the variables' names from the commit message.
  - 0010: Remove the detail typos from the commit message.

Changes in v2:
  - Collect "Reviewed-by:" from Tony.
  - Update the commit message of patch 9 to include the names of all
    variables that don't need NULL pointer initializations.

This series is based on the TIP branch ras/core with top commit 612c2addff36.

Thanks Thomas, Boris, Tony, Dave, Sohil and Nikolay for your review and discussion on this series.
