spi25: Use common code for nbyte read/write and block erase
Introduce spi_prepare_address() and spi_write_cmd() and use them in
nbyte_program, nbyte_read and block-erase procedures. The former
abstracts over the address part of a SPI command to make it exten-
sible for 4-byte adressing. spi_write_cmd() implements a WREN + write
operation with address and optionally up to 256 bytes of data. It
provides a common path to reduce overall redundancy.
Also, reduce the polling delay in spi_block_erase_c4() from 500s to
500ms as the comment suggests.
