That causes kernel to load its functionalities even if a chip isn't currently used. We plan to make each chip's functionalities a separate kernel module to reduce rtw88 core. And kernel will be able to load the necessary. Before extracting chip functionalities, we export symbols inside rtw88 core which will be used in chip modules.

That makes the pci module depend on chips. According to dependence, once the pci module is loaded, kernel will load chip functionalities, including those that may not be currently used. We plan to split chip entry points from the pci module. Thence we export pci symbols that will be used in chip entry point modules.
