Change Cypress linker script region name from .cy_xip to cy_xip

In some toolchains, in order to use linker symbols referring to the
start and end of a region, the region name must not contain a '.'
character. These changes allow those symbols to be used for the cy_xip
region by renaming it. They also create explicit start and end symbols
for GCC.
