mmc: sdhci-of-k1: Drop the use of sdhci_pltfm_free()

2025-06-24T10:43:25Z

Since the devm_mmc_alloc_host() helper is already in use, sdhci_pltfm_free() is no longer needed.

mmc: sdhci-of-k1: disable HW busy detection

2025-06-24T10:43:22Z

It doesn't make sense to enable HW busy detection in pre_select_hs400(), while disable it later in post_select_hs400(). And the reason behind this isn't clear. Therefore, let's disable it for now.

mmc: sdhci-of-k1: make register definition vendor specific

2025-06-24T10:43:22Z

Making register definition less generic which will potentially have less collision with other files. Add SpacemiT vendor prefix to K1 SoC SDHC register definitions, also improve the BIT definitions to reflect them more SDHC specific. Note, there should be no functional changes introduced in this commit.
