Subject: [PATCH v1 4/6] bus: mhi: core: Use common name for BHI firmware load function

mhi_fw_load_sbl() function is currently used to transfer SBL or EDL
images over BHI (Boot Host Interface). Moreover, its contents do not
indicate anything regarding support for a specific set of images. Since
it can be used for any image download over BHI, it can be appropriately
renamed mhi_fw_load_bhi() instead.
