Subject: [PATCH v9 0/2] phy: mediatek: Add PCIe PHY driver

These series patches add support for PCIe PHY driver on MediaTek chipsets.

Changes in v9:
1. Check if the return value is -ENOMEM when reading efuse data fails.

Changes in v8:
1. Use "device_property_present()" to increase human readability;
2. Use "GPL" as recommended in commit bf7fbeeae6db ("module: Cure
   the MODULE_LICENSE "GPL" vs. "GPL v2" bogosity").

Changes in v7:
1. Add bitfield.h header to fix the build error on non-arm64 platforms.

Changes in v6:
1. Remove unnecessary header files;
2. Use FILELD_PREP in bitfield.h to set value.

Changes in v5:
1. Fix typo in kerneldoc: "eFues" => "eFuse".

Changes in v4:
1. Fix no return when calling dev_err_probe.

Changes in v3:
1. Add introductions for structure members;
2. Add SoC dependent data;
3. Dynamically allocate efuse data;
4. Check return value if it's an -EPROBE_DEFER.

Changes in v2:
1. Add specific compatible name;
2. Read NVMEM data at probe time;
3. Fix typos.
