net: phy: microchip_t1s: add c45 direct access in LAN865x internal PHY
This patch adds c45 registers direct access support in Microchip's
LAN865x internal PHY.
OPEN Alliance 10BASE-T1x compliance MAC-PHYs will have both C22 and C45
registers space. If the PHY is discovered via C22 bus protocol it assumes
it uses C22 protocol and always uses C22 registers indirect access to
access C45 registers. This is because, we don't have a clean separation
between C22/C45 register space and C22/C45 MDIO bus protocols. Resulting,
PHY C45 registers direct access can't be used which can save multiple SPI
bus access. To support this feature, set .read_mmd/.write_mmd in the PHY
driver to call .read_c45/.write_c45 in the OPEN Alliance framework
drivers/net/ethernet/oa_tc6.c

net: phy: microchip_t1s: add support for Microchip LAN865x Rev.B0 PHYs
Add support for the Microchip LAN865x Rev.B0 10BASE-T1S Internal PHYs
(LAN8650/1). The LAN865x combines a Media Access Controller (MAC) and an
internal 10BASE-T1S Ethernet PHY to access 10BASE‑T1S networks. As
LAN867X and LAN865X are using the same function for the read_status,
rename the function as lan86xx_read_status.

net: phy: microchip_t1s: remove unnecessary interrupts disabling code
By default, except Reset Complete interrupt in the Interrupt Mask 2
Register all other interrupts are disabled/masked. As Reset Complete
status is already handled, it doesn't make sense to disable it.

net: phy: microchip_t1s: fix reset complete status handling
As per the datasheet DS-LAN8670-1-2-60001573C.pdf, the Reset Complete
status bit in the STS2 register has to be checked before proceeding to
the initial configuration. Reading STS2 register will also clear the
Reset Complete interrupt which is non-maskable.

never released to production and hence they don't need to be supported.
