Introduce additional SPI status register helpers

Browse Source 
- spi_prettyprint_status_register_default_welwip():
   It just prettyprints the plain hex value and the welwip bits.
 - spi_prettyprint_status_register_default_bp4():
   Prints the hex value, welwip, bp0-5 and srwd bits.
 - spi_disable_blockprotect_bp2_srwd(),
 - spi_disable_blockprotect_bp3_srwd() and
   spi_disable_blockprotect_bp4_srwd():
   Three new common block unprotection functions for the frequent
   cases where there is a status register lock bit at bit #7 and some
   block protection bits at bits #2-#4, #2-#5 and #2-#6 respectively.

Corresponding to flashrom svn r1681.
