spi25_statusreg: delete spi_read_status_register()
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.
Tested: flashrom -{r,w,E}
Tested: 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.
