8d1c65fce8 configs: am62x_r5_usbdfu: extend for AM62Px
Disable configs which are not required for USB DFU functionality, in
order to allow reusing this fragment for AM62Px SoC.

2beaa34252 configs/am62x_r5_usbdfu.config: More completely disable MMC
As this fragment turns off MMC in both SPL and full U-Boot, we can turn
the whole symbol off rather than just the MMC driver.

9b5ff131d0 configs: am62x_evm_*: Set DFU buffer size to 256k
OSPI flash writing was broken on am62x SKs as the OSPI flash device has a
256k sector size but was set to 20k. This breaks OSPI flash writes because
the current implementation of the SF DFU backend requires that the DFU data
buffer size be the same as the sector erase size, and the USB DFU config
fragment (for both A53 and R5) reduced the size of the DFU data buffer,
presumably so that it can fit into SPL's much smaller heap.

Change the SYS_DFU_DATA_BUF_SIZE to the erase sector size, which still fits
within the post-relocation heap size in SPL.

dfc2dff5a8 configs: am62x_evm_*: Enable USB and DFU support
Provide config fragments to enable USB host as well as USB gadget and DFU
support for a53 and r5. This relevant fragment is included into the
am62x EVM a53 defconfig. For the r5, due to the smaller available size,
the config fragment also disables support for persistent storage to free
up space for USB support. This fragment needs to be included is DFU
booting is desired.

The CONFIG_DFU_SF option is placed in the defconfig rather than the
fragment as this is known not to be supported on all boards that can
support DFU.
