spi25_statusreg: delete spi_read_status_register()

Browse Source 
Delete the spi_read_status_register() function because the generic
spi_read_register() function can be used instead.

This patch also converts all call sites over to spi_read_register().
A side effect is that error codes are now properly propagated and
checked.

BUG=b:195381327,b:153800563
BRANCH=none
TEST=flashrom -{r,w,E}
TEST=Tested with a W25Q128.W flash on a kasumi (AMD) dut.
     Read SR1/SR2 with --wp-status and activated various WP ranges
     that toggled bits in both SR1 and SR2.
