PHY_SPACEMIT_K1_PCIE has "default ARCH_SPACEMIT", but
PHY_SPACEMIT_K1_USB2, directly below it in the same file, does not.
Since the symbol is also absent from arch/riscv/configs/defconfig, a
plain "make defconfig" build for a SpacemiT K1 board ends up with the
USB 2.0 PHY driver disabled.
dwc3-generic-plat needs that PHY, so the result is a kernel with no
working USB at all on boards such as the Milk-V Jupiter, where all four
USB 3.0 type-A ports hang off the single dwc3 controller.
Give it the same default as its sibling.

phy-k1-usb2.c maps its registers with devm_platform_ioremap_resource()
and wraps them with devm_regmap_init_mmio(), but PHY_SPACEMIT_K1_USB2
neither depends on HAS_IOMEM nor selects REGMAP_MMIO.
REGMAP_MMIO has no prompt and can only be enabled by select, so a
configuration that leaves it off fails to link. In practice the symbol
is usually pulled in indirectly, which is why this has gone unnoticed.
PHY_SPACEMIT_K1_PCIE, directly above it in the same file, already has
the HAS_IOMEM dependency; without it PHY_SPACEMIT_K1_USB2 can be built
under COMPILE_TEST on architectures that provide no I/O memory.

The comb PHY on K3 requires to configure a syscon device for the
right mux configuration. And it requires calibration before any
usage.
Add USB3/PCIe comb PHY driver for Spacemit K3.

Commit fe4bc1a08638 ("phy: spacemit: support K1 USB2.0 PHY controller")
created spacemit subfolder with usb driver while commit 57e920b92724
("phy: spacemit: Introduce PCIe/combo PHY") added pcie driver in phy
folder. Move latter into spacemit subfolder and rename file to
phy-k1-pcie.c

The SpacemiT K1 SoC includes three USB ports:
- One USB2.0 OTG port
- One USB2.0 host-only port
- One USB3.0 port with an integrated USB2.0 DRD interface
Each of these ports is connected to a USB2.0 PHY responsible for USB2
transmission.
This commit adds support for the SpacemiT K1 USB2.0 PHY, which is
compliant with the USB 2.0 specification and supports both 8-bit 60MHz
and 16-bit 30MHz parallel interfaces.
