fix(sdmmc): fix invalid data when reading/writing PSRAM buffers

Browse Source 
Previous commit has enabled buffers in PSRAM for ESP32-P4. But this
also caused a regression for ESP32-S3, where PSRAM is not DMA capable.
This commit re-introduces the check for esp_ptr_external_ram in case
SOC_SDMMC_PSRAM_DMA_CAPABLE is not set.
