Subject: [PATCH v4 0/2] add regmap-spi-avmm & Intel Max10 BMC chip support

This patchset adds the regmap-spi-avmm to support the Intel SPI Slave to
AVMM Bus Bridge (spi-avmm) IP block. It also implements the usercase - the
driver of Intel Max10 BMC chip which integrates this IP block.

Patch #1 implements the regmap-spi-avmm.
Patch #2 implements the mfd driver of Intel Max10 BMC chip.

Main changes from v1:
- Split out the regmap-spi-avmm module out of intel-m10-bmc module.

Main changes from v2:
- Refactor the code of regmap-spi-avmm.
   - Rewrites the rx flow and simplifies the implementation, collapse some
     function calls.
   - Add bounds checking every time we fill trans_buf & phy_buf.
   - Try to configure spi mode on regmap init
   - delete regmap_bus.reg_write/reg_read callbacks.
   - Squash the bug fixing patch.
- Add the sub devices in mfd_cell for Max10 bmc driver.
- Improve comments and some minor fixes.

Main changes from v3:
- Rebased to 5.9-rc1.
- Collapse the phy buf padding code in br_pkt_phy_tx_prepare().

  regmap: add Intel SPI Slave to AVMM Bus Bridge support
  mfd: intel-m10-bmc: add Max10 BMC chip support for Intel FPGA PAC
