2020-05-15phy: amlogic: meson8b-usb2: Add a compatible string for Meson8m2Martin Blumenstingl
The 3.10 vendor kernel sets the ACA_ENABLE bit on Meson8b, Meson8m2 and GXBB, but not on Meson8. Add a compatible string for Meson8m2 which also sets that bit. While here, also update the Kconfig text and MODULE_DESCRIPTION.

2020-05-15phy: amlogic: meson8b-usb2: unset the IDDQ bit during PHY power-onMartin Blumenstingl
The vendor driver unsets the set_iddig bit during power-on as well and sets it when suspending the PHY. I did not notice this in the vendor driver first, because it's part of the dwc_otg driver there (instead of their PHY code). While here, also add all other REG_DBG_UART register bit definitions.

2020-05-15phy: amlogic: meson8b-usb2: Don't set REG_ADP_BC_ACA_ENABLE on Meson8Martin Blumenstingl
Skip setting REG_ADP_BC_ACA_ENABLE on Meson8 SoCs and polling for the REG_ADP_BC_ACA_PIN_FLOAT bit. The vendor also skips this part on Meson8 SoCs. This fixes initialization of the host-only USB PHY on Meson8 which would otherwise fail with "USB ID detect failed!".

2020-05-15phy: amlogic: meson8b-usb2: Use a MMIO regmapMartin Blumenstingl
Using a MMIO regmap and switch to regmap_update_bits() to simplify the code in the driver. Also switch to devm_platform_ioremap_resource() instead of open-coding it. No functional changes intended.
