To set it from -90° to 90°, just set it from -90° to 90° i.e. 

%Creating a random polar plot with same ThetaDir and ThetaZeroLocation as yours
theta = linspace(0, 2*pi);
rho = rand(1, 100);
polarplot(theta, rho);
ax = gca;
set(ax,'ThetaDir', 'clockwise', 'ThetaZeroLocation', 'top');

%Setting the desired limits
thetalim([-90 90]);

and if you want to have positive values for theta then you can change the ticklabels as follows:

ax.ThetaTickLabel = wrapTo360(ax.ThetaTick); %requires Mapping Toolbox
% or without Mapping Toolbox:
% ax.ThetaTickLabel(ax.ThetaTick<0) = split(num2str(ax.ThetaTick(ax.ThetaTick<0) + 360));
