PLASMA_sgetmi Implementation of inplace transposition based on the GKK algorithm by Gustavson, Karlsson, Kagstrom. This algorithm shift some cycles to transpose the matrix.

Parameters:

[in]	m	Number of rows of matrix A
[in]	n	Number of columns of matrix A
[in,out]	A	Matrix of size L*m*n.
[in]	f_in	Original format of the matrix A. Must be part of (PlasmaCM, PlasmaRM, PlasmaCCRB, PlasmaCRRB, PlasmaRCRB, PlasmaRRRB)
[in]	imb	Number of rows of the problem
[in]	inb	Number of columns in the problem
