MdeModulePkg:BaseSpiHcPlatformLib: Adding NULL lib instance

2024-05-08T04:43:58+00:00

Adding NULL SpiHcPlatformLib instance. This library is responsible for handling the low level details of the SPI host controller. Since this is platform specific this library will be dependent on OEM SPI implementation. The SPI host controller layer will utilize this library for SPI bus transactions.
