[PATCH v1 10/15] target/sh4: Drop use of gdb_get_float32() and ldfl_p()

["Alex Bennée" <alex.bennee@linaro.org>]

From: Peter Maydell <peter.maydell@linaro.org>

We used to make a distinction between 'float64'/'float32' types and
the 'uint64_t'/'uint32_t' types, requiring special conversion
operations to go between them.  We've now dropped this distinction as
unnecessary, and the 'float*' types remain primarily for
documentation purposes when used in places like the function
prototypes of TCG helper functions.

This means that there's no need for a special gdb_get_float32()
function to write a float32 value to the GDB protocol buffer; we can
just use gdb_get_reg32().

Similarly, for reading a value out of the GDB buffer into a float32
we can use ldl_p() and need not use ldfl_p().
