hw/arm: Remove unreachable code calling pflash_cfi01_register()

Since its QOM'ification in commit 368a354f02 ("pflash_cfi0x:
QOMified") the pflash_cfi01_register() function does not fail.

This call was later converted with a script to use &error_fatal,
still unable to fail. Remove the unreachable code.
